If an instinct or circuitry around revenge can exist in monkeys, I wonder if humans can ever fully escape that tendency, or if it is just built into who we are.
We can train ourselves. The methods are very old, but hardly anyone knows about them, much less actually does them every day. They are things like the Brahmaviharas.
When humans cull all the wolves in an area because they killed a child, we don’t call it revenge. We call it animal control.
The purpose of revenge is to cause pain.

Animal control tries to do just that, control. If a written sign would be enough, those wolves would not have been culled (except maybe the ones which actually killed tje child).

> When humans cull all the wolves in an area because they killed a child

Wolves normally don't do that. Not unless they have rabies. We should stop seeing the nature as if we were still in the XVII century.

The logical answer would be to direct the revenge against the real culprit, the rabies virus. Kill the rabid wolf and vaccinate other local wolves against rabies. Wolves learn quickly that must keep their distance with humans. Culling all the wolves in the area leads to more humans killed, by herbivores.

Why is it something humans must "escape"?
Revenge is counter-productive most of the time. It's only really useful when you want to galvanize a population into suicide.

Otherwise you get into a cycle of revenge for revenge for revenge that wastes everybody's energy.

"Revenge is counter-productive most of the time. It's only really useful when you want to galvanize a population into suicide."

Just offer a free vaccine that eliminates by heart attack and stroke 1% of the population group every year.

"Circuitry around revenge" is probably a beneficial social "skill" for facilitating group cooperation, there's all kinds of game theory (e.g. basic things like iterated prisoners dilemma tit-for-tat strategy) that suggests that knowing about the presence of revenge acts and a likelihood of punishing defection (even at extra 'expense' for the punisher) deters defection, and allows to reach a better shared result.

I.e. if we simply could abandon that at the flip of a switch, I'm not sure if we should, it's plausible that it would make all kinds of abuse less risky and thus more attractive, increasing the abuse happening in the world.

Macaques are very intelligent animals, more importantly they are successful because of their Machiavellian tendencies, just like we are.

Unfortunately while this behavior is useful at conquering the world, it becomes counterproductive later on.

HG Wells speculates about this in The Time Machine. The futuristic humans lost their revenge instinct and are helpless against their subterranean tormenters.
I don't remember the loss of the "revenge instinct" being a part of that book. The future humans had optimized for comfort/happiness so much that they evolved to be more and more docile and childlike. They lost their intelligence and evolved into stupid beasts again because they had no evolutionary pressure to become anything else. They didn't lose their self-preservatory instinct -- they just lost the only defensive tool humans have evolved that lets us compete/win against all other animals: our intelligence. Kind of like those birds in a New Zealand island that evolved to be too fat to fly, because the island had no predators. And then cats got accidentally introduced to the island.
Of course we can; the point of having such huge brains is that we can override our animal instincts if we want to. Same reason you can convince yourself to jump off a cliff into water even if you're scared of heights. Or how you can convince yourself to skip meals to get your work done. Or to not physically fight someone when you're in a disagreement. Or to not cheat when in a relationship.

Not being slaves to our animals instincts is kind of what makes humans human.

> villagers began attempting to rescue the dogs on their own. But some of them have found themselves subject to the monkeys' retaliation, and some have even injured themselves or fallen from buildings

how strong are these monkeys?

I mean I know monkeys are strong but can they really ambush a human, and push them over a ledge? can they kidnap a human, carry them upward and drop them over a ledge?

I think it’s implied that the people are just falling because they are startled or otherwise defending themselves against monkey strikes.
Have You ever tried to pull Yourself up to the top of a tree with 1 arm in 30 seconds?
Chimp muscles are stronger than ours but we are often stronger than them in absolute terms because we are bigger (more muscle mass).
We are not stronger, we have more stamina. There is a difference
We both are stronger and have more stamina than macaques. The biggest male adult macaques are 18kg. That’s probably more that the average adult can raise with one arm but not by much and I insist on average. That’s nothing exceptional for someone in shape.

Considering the weight and power in a human leg, a swift kick would seriously harm and probably kill an average macaque. The issue is not strength here.

The average adult can't lift 18kg with one arm, even with improper posture? That's pretty sad if true.
The average parent can definitely lift 18kg with one arm, that's the weight of a 3 year old...
More than half adults are women, a third live in Asian when the average weight of an adult is 58kg. You have strong bias.
We are not stronger than chimps. Our arms certainly aren't.
yes, a chimp could literally rip the arm(s) out of a human without a sweat. 1 chimp arm is roughly equivalent to 2 of the strongest human arms.
Chimps, no, but a small 20kg macaque, yeah definitely. You could yeet such a small animal, for lack of a better word. That's why they band together :)
> This result matches well with the few tests that have been done, which suggest that when it comes to pulling and jumping, chimps are about 1.5 times as strong as humans relative to their body mass. But because they are lighter than the average person, humans can actually outperform them in absolute terms, say O’Neill.

https://www.newscientist.com/article/2138714-chimps-are-not-...

Has little to do with strength.

Haftor can't really do this, but I'm pretty sure he can rip one of those monkeys in half if he catches it.

(comment deleted)
I'd bet a pair of them could pick up and throw a human; if they could get the co-ordination right.

50lbs of dog is a bad opponent for a human, 2 of them and humans lose that fight fairly often. Some of the dogs in the video I saw were that size and larger; so if the monkeys can harass and herd them effectively then I'd expect them to be able to do it to a human as well.

A human prepared to fight and ready to start killing things is a completely different matter; but I don't think these critters have encountered that yet. They're probably about to.

The article said the humans have "culled" about 1000 of the monkeys. It's interesting that we use different euphemisms depending on who's doing the killing.
In Malaysia not in India. In India, laws don't allow killing of even rabis infested dogs forget about monkeys. Not to mention monkeys are considered sacred.
(comment deleted)
IMO they don't need to be "culling," which would imply more "humane" means of killing like rifle shots or poisons. They need to go out and kill some monkeys in full sight of the other monkeys, in a personal and ugly way that the moneys understand. Swords and clubs time. Hang bits of the victims where the rest of them hang out.

Works for coyotes.

Drag them down to our level and beat them with experience:-D
pour les encourager les autres
The same term is used for cattle. I guess species at the top of the food chain choose the terms of art. I wouldn't be surprised, though, to learn that the monkeys have their own sound/ utterance to mean the killing of people.
What do you mean same is used for cattle?
He means “cull” is a term we use for killing cattle.
That's not precisely correct. With respect to cattle or any other domesticated ungulates, "culling" means removing from the herd. That might occasionally be slaughter, but usually means selling the animal. Of course the new owner might buy the animal in order to slaughter it, but we can't assume that.
We have different words for different types of killing. We say “slaughter” when we’re talking about killing a farm animal for food, and “cull” when talking about killing animals for the purpose of population management. Likewise we have “murder” for intentionally killing a person vs “manslaughter” for an accidental/less-culpable killing, and “euthanise” to describe killing something that is already dying so as to end its suffering.

What the article describes is accurately described as culling, or killing for population control.

culling actually means selecting out from a group on the basis of some criteria.

harvested lobsters with one claw have less commercial value so they are separated out. They are sold more cheaply and called "culls". A difficult entry level university course in an academic department like Chemical Engineering could be used to cull the class of students down to only those who are serious about pursuing the field; in such a case, the culls are not killed.

it's the nature of metonymy https://en.wikipedia.org/wiki/Metonymy that the word cull can take on extra meanings depending on the context.

They're macaques, so maybe they can handle small children. Not adults.
> how strong are these monkeys?

I believe the right question is, how intelligent and distempered are these monkeys?

Intelligence > brawn

Strength is mostly immaterial once I (as a hypothetical monkey) understand that I can use my agility to rip your eyeballs from their sockets, which then effectively removes your ability to pose a threat to me.

Weirdly specific.
It’s something primates do to human captors.
It's also something that humans notably do when fighting each other. Thumb in the eye is an instinctually intuitive move.
Really? Do you happen to have an article handy?
That's a silly way to think about it, strength just gives you more tools that you can work with if you're intelligent. If you aren't strong enough to rip eyeballs from sockets, how does being intelligent enough to know you can do that help you?
> strength just gives you more tools...

I believe the opposite is true.

If I'm smart, I will use your strengths against you.

I am not sure how you reverse body slam someone.
Judo and other throwing-style martial arts could be described as using "reverse body slams".
The stronger you are compared to your opponent the better Judo works not worse. The martial arts that use the opponents strength depend on the "opponent" being compliant.
"Everyone has a plan until they get punched in the mouth." (c) Iron Mike
Completely ridiculous. Intelligence matters in a fight, but raw strength is always more important. Try fighting a gorilla and see how you do.
> Strength is mostly immaterial once I (as a hypothetical monkey) understand that I can use my agility to rip your eyeballs from their sockets, which then effectively removes your ability to pose a threat to me.

Strength is material once you understand that this hypothetical human can use some kind of weapon or just something long and blunt to bash your brains out.

All wild animals are stronger than they look. Humans are comparatively weak.. most of us can’t fight a deer. Monkeys are intelligent. They are aware of leverage and potential danger. They jump on people, chase, scratch and bite them
Deer? Those are from 500 pounds to over one thousand pounds. Oh courses a person can’t engage in a physical fight with them.
In the San Francisco Bay Area, our native California Mule deer that commonly roam suburban streets, weigh in between 100 and 300lbs.
White tailed deer on the east coast and midwest are in a similar size range.
And the little Key deer down in Florida, which are the smallest of the North American Whitetails, are typically about 40-50 pounds. One night when I was down in the Florida Keys, typing away at my laptop on the beech in the dark, I felt something cold and wet touch my elbow. I looked over my shoulder, and a little Key deer was sniffing my arm. I jumped a bit, and then the deer jumped a bit, and with one last curious look, she ran off into the dark. Very cute little thing.
What deer are these? Deer in my area rarely weigh over 200 pounds.
I'm guessing you're from Europe, because what you call Deer, the USA call Caribou or Elk, and what we call Deer aren't nearly that big.
Male deer with antlers routinely gore dogs where I’m from. Deer, not elk.
(comment deleted)
Or he has seen Disney movies and thinks caribous are male deers.
Elk and caribou/reindeer are both kinds of deer (so are moose for that matter... for him to speak of 1000 lb deer, he must be thinking of moose or be mistaken.)
Any large dog is a lot to handle for most people should the dog get aggressive. Trained attack dogs demonstrate this quite well.
Attack dogs have a lot of core body / neck strength that they use combined with strong jaws. Definitely dangerous to an unarmed human.

The only thing you have on dogs is that you're smart enough to move to an advantaged position that the dog doesn't understand. Like run through a door and close it, get in a car and run the dog over, grab a gun and shoot the dog, those kinds of options. If you have no options, you're fucked.

I can't fight a pet dog that's 2/3 of my weight.
You could if you trained for it. You would probably be maimed after, though. That said these monkeys are more like 1/10th your weight
You hear that said but if you look at human prehistory whenever we encountered large animals they got wiped out and are mostly have to be preserved these days by conservation laws.
Trained humans working as a group with weapons, facing animals that have not seen humans before, is a completely different story. There is a reason African animals survived along humans while the story is different else where
> can they really ambush a human, and push them over a ledge?

I would say male adult monkeys in my village can (males are bigger and stronger), although they don’t. They are fast, agile and acrobatic. Except for well prepared adult humans, monkeys can throw everyone else off a ledge.

Reason so many monkeys exist in India is because they are sacred animals (to Hindus, 80% population). In our village, no one can kill them. The most one can do is throw a stone to scare them away.

Do you think this could change ?
Possibly but Hinduism is 4000 years old, so it might be a while before we see that change.
Where does the 4000 figure come from?
The Vedas are supposedly that old
Yes, but (without being a scholar of religion) I had always assumed that Hinduism was far older than its oldest surviving texts, just as Judaism, in some form, is older than whatever year we date the Torah to.
it depends on what you call 'hinduism'. it's one of the world's most heterodox religions and has absorbed a huge amount of cultural tradition from at least 300 languages.

The rig veda is probably what most people agree is one of the foundational texts of hinduism, but it dates to about 1500 BC.

However, the vedas probably absorbed a lot of earlier cultural tradition from the indus valley civilization, especially worship of Shiva-like deities. How much is however, debated.

just like mesopotamia, there was a lot of syncretism.

I imagine that when your career is arts based, you've likely assimilated that society's labels are arbitrary and determined in large part by competitive interests, because there is less of a fundamental truth than they would imply once established. Since this is a software engineering forum, we tend to expect more objectivity in our labels. Ironically when you think about it because software labels are so obviously artificial.
I thought the jury was still out on whether the so called Pasupati seal actually shows Shiva
My read is that it's the other way around. i.e. what one could reasonably call Judaism is a good deal younger than the Torah, Hinduism a good deal younger than the Vedas. There are of course traditions within the religions that go back to those writings and further, but take that to its extreme and they all presumably stem from some ur-religion.
I guess like so many questions it comes down to how you choose to define and name things.
yes, could happen.

modernity tends to change culture (and especially homogenization that the interwebs promotes), and india is modernizing rapidly especially cities. culture can change very rapidly.

that being said, hanuman (rama's monkey companion) is a important diety in hinduism, and has been worshipped for many thousands of years in india and other parts of southeast asia.

https://en.wikipedia.org/wiki/Hanuman#Historical_development

Strength doesn't come into the picture with monkeys. They attack by biting and scratching and often from hidden places like tree tops or rooftops. In many parts of India, the dogs are afraid to even bark at them.

That said, adult monkeys are pretty big (3.5-4 feet) and aren't all that light weight.

Anecdotally, a baby monkey fell into our neighbors house through bars on the roof and a group of almost 100 monkeys surrounded the house and took them all hostage till the baby was given back.

That is some "planet of the apes" level situation
Add a mysterious global virus to the mix and you have a movie. Oh wait, that's reality.
well, the anxious animals got the baby back.. I am certain the monkeys did not ask nicely! but let's look at it differently, the monkey pack acted together right away for the safety of the smallest one.. did they hurt the humans? the story does not say that; a more aggressive animal would certainly hurt a human right away for the sake of a small one.. but those animals have been hunted and removed.. +1 monkeys from me
(comment deleted)
The story does say: Now, villagers reported that the monkeys are targeting small children which has created a panic within the village.
We don't know the whole situation. Article says "villagers began attempting to rescue the dogs". But how? May be villagers tried to attack monkeys and they felt threatened.
(comment deleted)
> These people need guns

this exactly is what I have to deal with in the USA for neighbors.. small wonder anything larger than a dog is now extinct in most of North America.

meet up at the big truck rally

But how do other monkeys know they participate to a legitimate cause? They don’t have language to express reason, facts, inferences or values.

Which strikes me, because they really did “ask nicely”, not attacking humans and behaving in a measured way. Where I’m coming from is:

Is language necessary? Human crowds are most often fair (doing a revolution is quite fair, even if individual events are a bit… messy. But crowds stuff up sometimes, ie Jesus vs Romans). Might we (humans) act about as fairly if we didn’t have language at all to express our griefs? All that bullshit that goes on in courts, sometimes fair sometimes not; all the bullshit that goes on in companies about metoo: Does it “average out” the same as a crowd of angry monkeys, or are we effectively more efficient at delivering justice? Is our language a vehicle for reason, or is it just a vehicle of feelings and anger that happen to translate itself into words that seem rational?

> But how do other monkeys know they participate to a legitimate cause?

The legitimacy of a cause depends on your value system, and who is to say what sort of value system the monkeys have. Perhaps their value system places "stick up for other monkeys" before other considerations like impartial assessment of guilt or blame.

"How many two year old...monkeys could you take in a fight?"
if a monkey tries to hurt my dogs, i will fight to death for them. mentally they are my children.
The Langoor monkeys are really strong and I have personally witnessed their menace. There are countless instances I can recall where the monkeys attacked humans, pets etc.
A small lovely looking gibbon can break your arm off your body easily.
If the monkeys start pushing people off buildings that seems like an escalation? If war breaks out between the monkeys and the humans - I’d think we’d have a decisive advantage?
Yes, as soon as humans start dying from monkey attack someone will call wildlife control and either capture and move the monkeys (hopefully) or shoot them all.
My guess is that in these cases, the humans put themselves into a vulnerable position in pursuit of the monkeys.
Pound for pound they are about 1.5X stronger than humans due to the density of fast-twitch muscle fibers. This also makes them quicker and more nimble.

If they attack from behind they can easily knock down an adult human. They use this tactic to attack motorcycle delivery drivers quite often and steal food. They would have no trouble nabbing a child.

With small children, sure.

With bigger humans, they don't need to throw them. It may be enough to drive them strategically by screaming and biting in a big enough group and with an unprepared enough victim.

> how strong are these monkeys?

One, or even two monkeys won't usually attack or even threaten an adult male. Although, a monkey will easily beat an adult male human.

They are like 2-3.5 ft, and weigh at least 20 kg.

They are also sneaky. You will be bitten and scratched badly, and will be fighting for life.

One monkey cannot lift a human.

I have lived in a monkey infested area for decades, and I have never even heard of someone dying by monkey attack.

They also come in packs. They totally avoid directly messing with humans. But if some reason is given, then they can attack.

I think they cannot lift a full grown human being. Or kidnap one.

I think these injuries are from people getting on the roofs by themselves to save dogs, and falling due to bad control, panic, being attacked, or all.

> at least 80 kg

Are you sure? That's on the big side for a human.

Need to correct. Thanks for catching.
I’d like to see these Monkeys try and capture my 54kg (129lb) Doberman. He is ridiculously strong, has broken a few collars and is impossible to move if he decides to stay put.
Monkeys are ridiculously strong and vicious when they go to war in groups.
I don’t think Indian villagers would be thrilled by your dog if they had to feed it
Sorry buddy, but a troop of larger monkeys would tear any dog to shreds -- doesn't matter the breed or size. They're fast, strong, agile, and smart.
An article on the internet tickled the same insecurity trigger that led you to adopt a tough guy dog in the first place. Observe yourself a bit more.
Read also a study of car makers on correlation of big SUVs and insecurity.
Great insight. I wonder if it applies to him. Perhaps the dog was gifted to him without any choice of his own.
There’s alway a choice. For example a choice not to accept a doberman puppy.
> Observe yourself a bit more.

This sounds really condescending, Please lets don't do this here. Everybody is free to have exactly the dog that they want. Period.

I can't see the need to invoke the dusty ghost of Freud all the time with those dumb clichés. In the real life, not all is always related with penises.

> I’d like to see these Monkeys try and capture my 54kg (129lb) Doberman.

You're saying you would like to see a pack of monkeys attack your dog? Your post is either internet bravado or an injunction for someone to call and alert animal welfare about your conduct.

Is obviously an hypothetical situation expressing that the dog would strike back if attacked.

And yes, the dog could kill some macaques easily. Stray dogs are often malnourished and weak. A well feed dog of a respectable size in open field is a different situation.

Philosophical question, assuming kt's not a fake news: are those monkeys "evil"? If they revenge is agains siblings of the aggressor or just dogs in general, I would say so. Looks like they are intelligent enough to be evil.
A terror attack on Christmas parade revelers in Wisconsin is what?
> evil > profoundly immoral and wicked.

I think the concept that animal can be moral / immoral is already a philosophical subject. See the book "Can Animals Be Moral?" for reference.

And in order to say that these monkeys are evil, you must first prove that they can be moral.

Which is to say they know right from wrong.

I doubt it

"Law of the jungle" and all that

It depends on whether you view evil as something absolute or relative.

If evil is absolute, then an animal (or an entire species) can be seen as evil by nature. Another species may be seen as good or neutral by nature even if the animal itself has no sense of right or wrong.

It is indeed very philosophical and also up to your beliefs and values.

If it's evil for primates to kill 250 dogs after one primate infant was killed is it evil for primates to kill 17 million minks because they could get a virus and theoretically spread that to primates?
Take into consideration though that these minks were bred specifically to kill them for their skin.

The end outcome was a ban on mink farms which is a pretty positive one for animal rights.

I also think the e culling of all those minks was horrible but it's not as black and white as that.

That ban was going to happen anyway, but in 2024.
> Take into consideration though that these minks were bred specifically to kill them for their skin.

Is that not much more 'evil', to breed something specifically to kill it for its skin? If it's not, then why is it not allowed to be done by the same species to itself?

> Is that not much more 'evil', to breed something specifically to kill it for its skin?

That depends on what value/s you place on the thing being bred for its coat. Pretty much all cultures around the world are different, subtly or dramatically, on such issues.

> If it's not, then why is it not allowed to be done by the same species to itself?

The answer to that is: because the humans judge that the minks (and their existence) are not equals in value to the humans, rather, they're considered property, to be disposed of as the owner sees fit. And obviously that aspect (as the owner sees fit) varies by location/culture.

Your question - then why is it not allowed to be done by the same species to itself? - starts from the incorrect premise that values are objective, such as whether a mink should or should not be considered property (your premise requires starting from the notion that minks have protected rights and are equal to humans generally). Instead, those values are in fact subjective and will vary depending on which culture you're dealing with.

Probably yes. I think both are pretty bad. I eat pretty much vegetarian for this reason (not entirely because here in Spain it's impossible to be totally vegetarian especially when you go out for dinner)
Curious where in Spain you are. I'm vegan and was looking at spending some time in Spain (mainly Granada at one point because of low cost of living, location, and availability of vegan food). In the bigger cities, Happycow shows hundreds of fully vegan and vegetarian restaurants.

As of yet I haven't actually been to Spain, but from traveling around Europe I did learn that eating vegan can (sometimes) be incredibly challenging. In a smaller coastal city in Italy I remember one night where the only food I could find to eat was a tomato salad (modified by removing all the non-vegan ingredients from a salad menu item).

But overwhelmingly through my travels I've been able to find more options.

I'm in Barcelona.

There are many vegetarian and vegan restaurants, yes. But when I go out for dinner with my Spanish friends they wouldn't pick those places. They'd always go for traditional places.

Which means you end up with exactly the kind of thing you mention "Uhhh yeah we might have a salad for you" :D

I'm not strictly vegetarian so it's not so much a problem but I had a colleague who used to come with us for lunch who got fed up with that.

But as a tourist you'l be fine yeah.

I'm from the Netherlands myself and the supermarkets there have a huge range of vegetarian and vegan foods. Here it's usually a corner of one of the fridges.

Bad example, those minks were going to be killed anyway, that's the single reason so many of them were allowed to exist in that place to start with.
If you're going to go that far, maybe they are just trying to encourage the dogs to self-regulate.
To me it sounds more like a straw that broke the camel's back moment. They've had enough and they can't take it anymore and are lashing out in a madness of grief and rage
Why are they evil? Or at least more evil than humans? Humans have eradicated wolves almost everywhere due to the danger they pose humans, particularly children. How is this situation different? The monkeys are even targeting the very same species that humans have long targeted.
The problem you have here is that your conception of this requires the potentially-'evil' to be intelligent - your assumption seems to be that these monkeys are smart enough to 'know right from wrong' or some such.

But 'evil' is a human concept. I'm not saying some animals aren't capable of having a similar concept, but 'monkey evil' would not be rooted in the human evolution of societies, religious and philosophical traditions, etc.

Try this one out:

Are humans who kill monkeys for science "evil"? Not to (many) humans. But to monkeys?

(comment deleted)
To begin to answer that you would need to start out by defining what you mean by ‘intelligent’ and ‘evil’, since both are subjective concepts that only exist relative to your perspective.
I'm not sure if monkeys experience revenge the way humans do. As one of the comments mentioned in the article, it's probably just a survival instinct.
(comment deleted)
I doubt that. Try shooting an arrow at a crow (obviously not killing it) or throw a stone at a group of monkeys the next time chance presents it self. Not a good idea. One of my childhood nemesis were a group of crows from a tree nearby at which I shot an arrow with a home made toy bow (none were even hit). Those things harassed me for months before eventually forgetting (forgiving?) the incident :)
Sounds like a story I once read in a children horror book.
Corvids are interesting, I've definitely been checked out by the ones in my neighborhood.
(comment deleted)
It is also possible to make friends with crows. You should have brought an offering of roasted nuts, and they would likely have made a truce.
> throw a stone at a group of monkeys the next time chance presents it self

In places like the Monkey Temple in Bali that's exactly how you keep them at bay. In our local zoo where you can interact with lemurs, they can be chased away with a small water spray.

been there with crows. they attack you for a month or so.
Snakes too.

The general belief here in India is if you are hurting a snake, might as well kill it, and then burn it, just to be sure.

Perhaps revenge is just a survival instinct that humans sometimes try to suppress through "logic".
How would humans experience revenge differently? What makes you think revenge isn’t an instinct in humans?

I recall reading (the book escapes me), that just about all animals employ a Tit-for-Tat mechanism for dealing with other animals of the same species that cheat.

Revenge is a very useful social tool, especially against other species threatening their offspring.

Dawkin's The ancestors tale?
> What makes you think revenge isn’t an instinct in humans?

An instinct is something you have no choice over, it's automatic.

Humans very clearly have a choice as to whether they pursue revenge or not. If someone wrongs me in a given way, I can choose how to respond, or to not respond at all; and I can spend as much time as I like (decades if I choose to) pondering on that. It's doubtful these monkeys function quite at that level.

It's unknown whether, for example, these monkeys have any choice in the matter. Their programming may be purely instinctual when it comes to a revenge response.

> An instinct is something you have no choice over, it's automatic.

I think this is a common but entirely wrong model, and I'm not sure why people hold it.

Do you think humans have no instincts? I would argue exactly the opposite, humans, like all animals, are driven almost entirely by instinct, whether it's prosocial instincts causing you to have a moral code much like those around you, inspiring guilt and shame when you break it, or causing you to feel a need to talk to people and comment on Internet stories, reproductive instincts driving you to seek a mate, or survival instincts to ensure a regular food supply.

I think it works exactly the same way in all animals. They are equally capable of making choices, because choice is a preconscious thing, not something that occurs as a result of careful, reasoned intellect. Obviously, humans are capable of making more informed choices, but "reason" is mostly a post-hoc rationalization engine.

Most animals are capable of revenge. Story: A family in Palestine were doing a routine cleaning of the house. They had a snake nest in the house and it was no pet snake. So to clean better they put the nest and eggs in a different corner.

The snake came back looking for the nest and could not find it. It looked around with no luck. It went to the family water vase (because there was no piped water supply) and spit inside. The mother saw this and told the other to put the nest back.

The snake saw the nest, went immediately back to the vase, coiled it and flipped the water over over to empty it.

It had spit poison in the supply to hurt the family for revenge of its nest. And then sought to undo that act.

That's an interesting story, albeit one that sounds like a good fairy tale. Any source for this?
While normally people differentiate 'venom' from 'poison' to be pedantic, I don't think snake venom is particularly harmful if ingested.
I know a member of the family first hand through my workplace who told me and a few others. The guy was about 55 years old at the time (7-8 years ago) when he narrated the story. He was a Palestinian but in Jordan at the time it happened and was there before he reached age 18. (I should not have stated he was in Palestine.) I am not sure what other details I can provide beyond name for this narration.
I'd be surprised if snakes have the capacity for that kind of reasoning.
Why do you say "probably"? Do we have any evidence on which to base our presumptions of the inner experiences of monkeys?
The extremely similar brain structure of all mammals?
But then wouldn't the similar brain structure between monkeys and humans point towards monkeys' qualitative experience being more similar than humans than the other way around?

I'm not trying to argue one way or the other, but a matter such as this seems plagued by uncertainty and it seems rash to me to be making such presumptions.

> But then wouldn't the similar brain structure between monkeys and humans point towards monkeys' qualitative experience being more similar than humans than the other way around?

I'm not sure what you mean. Did you forget a word?

Sorry for being unclear.

The original post presumes that monkeys' experience of revenge is "just a survival instinct". I find it quite odd to make such a strong assumption about something as unknowable about conscious experience (perhaps wrongly if there is evidence to that effect I am not aware of).

Your reply pointed out that mammals have similar brain structures. To me, this would imply that humans and other mammals (particularly monkeys) should have more similar experiences of the world as a base assumption, rather than leading us to dismiss similar behaviours as survival instinct etc. Perhaps I missed your point?

I can see that this is quite hand-wavy topic, but hopefully this helps to clarify a little.

My great grand uncle is known in my mother's family side for getting killed by a camel that he mistreated years earlier. He apparently was usually very gentle with his camel herd but at some point that particular male didn't want to move so he hit him with a cane, and years later when he was working behind that male again he just got stomped to death.

I'm sure the story has been "embellished" a bit though and there's probably tons of confounding factor but I've heard a lot of similar stories about camels and their famous penchant for revenge :).

Baboons have been know to kidnapping puppies too. They live with the troop and offer protection as warning/guard dogs.

https://www.youtube.com/watch?v=U2lSZPTa3ho

Wow. It might be possible that our relation/domestication of dogs started well before we become sapiens. Because, why would the baboons pick a dog and not a tiger.
Great... Now even the monkeys have a functioning justice system and we don't.
A devastating rampage of monkeys? I can think of some parallels.
Trying to wipe out the other side is "a functioning justice system"? It was in 1942 after Reinhard Heydrich's killing.
How is that a functioning justice system?
At least they punish the perpetrators... They over-punish whereas we under-punish. Under-punishment is worse because it implicitly punishes those who do the right thing by allowing perpetrators to get away with crimes; it encourages crime. Just wait 10 years and you will understand what I'm talking about. You severely underestimate how bad things have become. It will dawn on you suddenly like a nightmare from which you can't wake up.

Maybe this comment seems alarmist but I'm trying to help. Read it with an open mind and a grain of salt. Better be alarmist than sorry.

Why are people surprised and shocked by this? If a pack of stray dogs killed a human child, we would exterminate them without further thought, and we would call it "animal control." Even when an otherwise protected species like a bear in a national park kills a human, we make an exception and kill that animal.
> Why are people surprised

Who said anybody is surprised?

It's posted to HN. You wouldn't see "${western_city} Animal Control Removes Stray Dogs from Park After Child Killed" on HN.
It's newsworthy because it's unusual, not surprising
And neither would you see headlines about a human child learning to read, yet if a monkey were to do the same it'd be up here in no time. The noteworthy thing here is not the activity performed, but what entity the activity was performed by.
This is not a small group of dogs, but a prolonged war between two species.
Um, because it was monkeys that did it, not humans? And humans =/= to monkeys?

It's surprising because (a) we generally consider revenge to be a human emotion, so seeing it in animals is a bit surprising, (b) seeing a coordinated attack between two species that are kind of adjacent on the food chain isn't super common. Killing in the animal world is primarily done for hunting. The monkeys aren't eating the dogs, they're just killing them.

This sounds just like human behavior of retribution in the mob and street gangs. Or even Twitter. Fascinating.
I remember from a visit in Kenya that the way they control monkeys was to keep shooting the alpha until eventually their next leader forces the group to retreat and leave the human settlements alone.
Wonder how many times this has been done with humans throughout history
When America was trying to install a “democratic” government in Iraq there were a series of assassinations. In that case however the situation eventually stabilized.

So that strategy is only as good as your opponents will. And it turns out there’s a lot of men who are willing to throw away their life in the hope of the power, money and prestige of being the top boss.

I wouldnt be so quick to say they're throwing their life away. Imagine being in a group with a tyrannical boss. Installing yourself as the boss may actually help save your life and ensure a future for you and your community/tribe.
Regardless, I wonder if there's a lot of men is the key factor here. Even if a reasonable fraction of a percent of the population isn't deterred by previous assassinations for a population in the millions, that's still a lot of replacements. The replacement rate of that subset of the population is almost certainly higher than the assassination rate.
I don't doubt that gambling it all for power, money and prestige is the most frequent motivation, but I think you do humanity a disservice when you don't also include principled... weirdos that believe things and count the cost do exist within the human race.
The assassinations in the 60s serve as examples.
There's no equivalency.
It appears to contribute to our decreasing brain size for the last 17k years.
>Villagers reported that now there are barely any dogs left in the area but that the monkeys have not stopped even after a month of attacks. Now, villagers reported that the monkeys are targeting small children which has created a panic within the village.

That's when you start shooting these monkeys on sight. Cull their numbers a bit. I've been bitten by a monkey as a child and it sucked. I hope the village starts splitting their wigs. Do they have guns?

I grew up and studied in a University town in Central India, not far from Majalgaon FTA. I've personally witnessed the rivalry of the monkeys and the pariah dogs. In one particular instance a youngish dog was chasing the monkeys and wouldn't let them get on the ground. The leader of the monkey gang made a sudden move, swooped down and carried the dog pup on the tree and just dropped it from there. The pup survived and the dogs never tried to attack the monkeys after that instance. It was such a surreal scene that me an my friends couldn't believe what we witnessed. Monkeys, esp Langoor monkeys are a fearsome force in India and not to be messed with.
> Langoor monkeys are a fearsome force in India and not to be messed with.

I thought langoors were more friendly towards humans compared to macaques?

As a general rule, animals never attack first. When humans encroach the traditional lands of the animals there are conflicts waiting to happen. Monkeys are smart and usually don’t bother humans, unless it’s a matter of food or threat to their group.

Edit: I'm surprised at the downvotes, isn't human-wildlife conflict in Indian forests well documented?

At least one animal does. Homo sapiens. We are not separate from nature, we are just a extreme of nature.
That's one interpretation of the word "animal". The use above clearly meant non-human animals.
More generally, all predators do. We aren't the relentless killing machines that cats are though.
As a general rule that’s true but useless. Humans are relatively large animals that most creatures don’t want to mess with. But a hippo for example isn’t discouraged by this.

Also the deadliest North American wildlife is the deer almost entirely because they’re jumping in front of cars.

> Also the deadliest North American wildlife is the deer

Actually, the deadliest North American wildlife is the mosquito.

Are they particularly deadly in NA? I’m not downplaying the disease spread by mosquitoes, but I would have imagined that they’re significantly deadlier in less developed continents and that then acesss and quality of healthcare would make them less so in North America.
Depends on what you consider North America. Mexico down to Panama still have significant mosquito-borne illness and none of the access and quality of healthcare we enjoy in US/CA.
Mexico with a population of 130 Million only had 641 cases of Malaria in 2019, it’s not at great risk from mosquito-born illness. Central American countries are at a significantly higher risk, Panama for example has 4.4 million people and had 1,597 cases of malaria in 2019. Other diseases show similar trends.

Still in terms of total deaths from Mosquito born illness it’s likely lower than most assume.

Personally, I consider Mexico, Canada, and most of America as North America with the Caribbean, and Central America being separated.

I wouldn’t call Malaria etc wildlife, mosquito’s on their own are harmless.

Malaria was once endemic in the US, but that was a while ago, right?
As a general rule stray dogs and wolfs in packs will attack humans.
They big mad if you say humans are killers. The monkeys would do that to any species once threatened.
This is some nature is benign nonsense. Plenty of animals will attack humans without provocation. E.g., mosquitoes are animals. More seriously, stray dogs etc. attack children quite regularly in India. Man eating tigers etc are documented to track down and hunt humans.
>As a general rule, animals never attack first.

Nonsense. There is a long list of predator species that will opportunistically feed on humans.

As you yourself point out, many other animals that can't eat a human will attack if they feel threatened or competition.

Be careful around all large animals.

I would expect most animals that still exist to at the very least not be a major threat to humans - because if they are, they tend to cease to exist.
Depends on your definition of major. Mosquitoes still exist despite nearly a million people dying from the diseases they transmit each yaar.

Stray dogs in India are responsible for tens of thousands rabies deaths annually. Yet it's illegal to cull them.

I'm surprised about the stray dogs.

The mosquitoes are being worked on.

> I'm surprised about the stray dogs.

It gets worse. A court recently ruled that Resident Welfare Associations are now legally obligated to feed and look after stray dogs in their neighborhoods.

A good judgement in my view. Culling dogs isn't the right way to end this. Sterilize them and let them live their lives out.

This is going to be the humane way of ending this menace that will also be culturally acceptable.

> A good judgement in my view.

Just so I'm clear: You think it's a good idea to foist the responsibility of feeding and looking after street dogs onto resident welfare associations? Many of which actually want them removed? Their member are being asked to pay up for the privilege of being harassed by dogs.

To quote none other than Mahatma Gandhi on the subject[0]:

> It is a sin, it should be a sin, to feed stray dogs, and we should save numerous dogs if we had legislation making every stray dog liable to be shot. Even if those who feed stray dogs consented to pay a penalty for their misdirected compassion we should be free from the curse of stray dogs. Humanity is a noble attribute of the soul. It is not exhausted with saving a few fish or a few dogs. Such saving may even be sinful. If I have a swarm of ants in my house, the man who proceeds to feed them will be guilty of a sin. For God has provided their grain for the ants, but the man who feeds them might destroy me and my family. The mahajan may feel itself safe and believe that it has saved their lives by dumping dogs near my field, but it will have committed the greater sin of putting my life in danger.

> Sterilize them and let them live their lives out.

Sterilization isn't going to come cheap. This will only end up diverting funds from municipal governments that are already perpetually short on funds.

> This is going to be the humane way of ending this menace that will also be culturally acceptable.

Except that it simply doesn't seem to be working. ABC measures have been going on in large cities for years but from what I can tell, the numbers just keep going up. There's a reason the rest of the civilized world culls strays. This is what India did too until Maneka Gandhi got her grubby paws on the AWBI. There isn't some deep seated cultural opposition to culling, it's the the result of morality pushed by privileged animal lovers. There are an estimated 6 million dog bites in the county each year. Most victims are children from poor families.

>>Resident Welfare Associations are now legally obligated to feed and look after stray dogs in their neighborhoods.

The best way to stop stray dog menace, just stop throwing food/organic waste on the streets.

Stray dogs quite literally survive on this, and I remember my childhood stray dogs used to be all pervasive during the days of corner garbage dumps here in Bangalore, now that we have garbage picking up waste from homes in most areas, they are almost non existent in those areas.

Take away their food, they go away.

> The best way to stop stray dog menace, just stop throwing food/organic waste on the streets.

I don't know to to respond to this. Garbage has nothing to do with it. There are now organized groups of people who literally drive around, feeding dogs in the streets: https://mylosrescue.com/feeding-initiatives/ In addition, the courts have imposed the obligation on RWAs to feed stray dogs if nobody else is doing so.

These monkeys are not fatally dangerous if that's what GP is saying.

But they cause heavy and serious nuisance.

Where I live, these monkeys invade gradens, agricultural fields, house rooftops at least 4-5 times a month.

The locals drop anything they do, and chase away these monkeys.

When chased by an adult male human, these monkeys don't fight back and are easily frightened. They don't mess with adult males or groups of humans.

A kid or a lone woman is not safe, though. When faced by them, monkeys gesture retaliation, and that is enough frightening.

An adult male cannot physically take on a monkey. It is impossible. Still they don't attack.

They steal bananas, mangos, guavas- all kinds of fruits, any food item not indoors, and destroy flowers and plants.

Thus, for families depending on these as their source of income have to always remain vigilant to monkey invasions. Common methods include- stone being thrown directly at them intending full harm, pebbles thrown by slingshots, and firecrackers. Banging metal objects loudly also seems to help.

We have mango groves that we lend on a yearly basis. The people who lease them from us establish outposts during the mango season which are always manned by at least one man with ready reinforcement in case of monkey invasion.

For those families not depending financially on tree products are also harmed. They make growing flowering plants difficult. They steal food from outdoors, and not to mention the awfully smelling solid and liquid excretion they leave on your rooftops.

(All rooftops are flat in the plains region, and they are important in our lives.)

By the way, I lost one pomelo (Citrus maxima) to a bunch of monkeys this very afternoon.

I understand but aren't we to be blame for this? We took their home, we took their shelter and what can they do? And they don't have enough wisdom to know who they should harm and who they shouldn't.

And many of monkey i know here are too friendly but yea after they starts to live with humans they learn to hoodwink people because many thieves are known to use monkey to snatch valuables from tourist by providing bananas as incentives to them.

> We took their home

We are an animal and part of nature too.

> And they don't have enough wisdom to know who they should harm and who they shouldn't.

They seem pretty smart about it tbh. They know what they can get away with and go no further than that.

There have been articles, probably also threads on HN, about monkeys enslaved and used to harvest crops or something. I don't remember all the details, but they pull out their teeth so they can't bite, and coerce them into working much faster than humans could.
> An adult male cannot physically take on a monkey. It is impossible. Still they don't attack.

Are you positive?

A chimpanzee: yes. A guerilla: indubitable. But a monkey?

They seem like medium-sized dogs, that can move around quicker and more freely. They'll bite out your flesh, and perhaps maim you to a semi-serious degree (including infection), but I cannot fathom a monkey seriously killing a grown adult male human being.

These are 20-40lb, very aggressive racoons. If you shock them with anything, they're most likely going to flee for fear of serious injury.

> But a monkey?

Oh boy never test this out. They will attack violently and will not spare you. If they have enough numbers or have the pack leader(usually the one with the biggest balls) close by then they will retaliate. I'm from south India and I have seen a lot of grown up men get roughed up by monkeys

"roughed up" sounds like getting a beating. but I'd assume they rip your face off and stuff. care to elaborate?
Yes they will scratch/bite you a lot. But they'll leave you after a while. They're not extremely violent like predators eating us. They only retaliate
A Macaque, maybe 15 kg in weight, has the aggression claws and muscle to take on any non-beefy human and win, not doubt about that.
Win, or injure the human so badly that they won't pick the fight again before the human kills it, assuming the human actually fights to kill?

I have no doubt it's not wise to fight a monkey, but I wouldn't expect it to actually win.

Male macaques also have very large canines, and massive jaw muscles to use them. A bite that severs a major blood vessel could end very badly.

They also move a lot more...three-dimensionally than you might imagine, making it hard to predict where they're going.

I've been looking through monkey bites, and they're a lot more tame on human skin than they are on other monkeys.

Macaques have large teeth and strong jaw muscles (as do dogs); but unlike dogs (or say even piranhas), it doesn't look like monkeys rip and tear flesh like canids. Their mouths are a lot like human mouths: incisors in the front, two canines on either side, and a bunch of (pre)molars, indicative of omnivores. The two canines will definitely pierce the skin. The incisors, most likely as well; but the molars are absolutely useless here.

Whereas dogs (and more specifically sharks) have "saw-like" teeth, that combined with strong neck muscles (and a propensity to grab hold, and shake vigorously, as if they're literally sawing away flesh), make them a lot more lethal to most land mammals.

If we include monkey eating habits, I don't see any large mammals on the list (all the mammals they may eat are smaller than them); compare that to the canid family, that will hunt down mammals many times larger than them. I just don't see how the monkey is built to be able to kill a human being.

Granted, it's going to hurt a lot to get bitten by a monkey. But I just don't see how a 40lb mammal can do that much damage. If you can somehow restrain it by the neck, it's basically over for any mammal of that size without claws (or another means of escape) -- which monkeys don't seem to have.

Now, if we're talking a chimpanzee? I'm going to do everything in my power to get out of that situation. But a monkey? A large dog is more of a threat.

That's all well and good until 5 of them jump on you and sink 2 inch canine teeth in you...
I feel after the first few bites, you'd be running on adrenaline.

At that point, I believe it's apt to start elbow-dropping, curb-stomping, and punting monkeys.

If for some unknown reason, 5 monkeys ambushed me on a regular walk, I'm confident I could throw enough of a fuss that'd dissuade them from trying to steal my lunch.

Now 10 monkeys? I don't know. That's a lot of monkeys.

I don't think I'm ever going to encounter 10 monkeys, all set on turning me into tartare.

However, if I were to have my jimmies rustled by 10 monkeys at the same time, I would put it at 2:1 odds that I survive without life-threatening injuries.

I would agree that you could dissuade a few monkeys from taking your sandwich. Animals don't particularly want to fight: even a "victory" could end badly if you live in a world without antibiotics, splints, or indeed any medical care.

On the other hand, if you backed five desperate monkeys into corner so that they think they are fighting for their lives, I think you'd fare much worse. I'd bet "punt attempts" sometimes end with the monkey clinging to your leg instead, chomping away at whatever they can reach (and even the molars can do some damage given the tremendous bite force).

As an adult male, I’d rather not get my flesh bitten off or maimed. So I cannot engage in a fight with any monkey. The only fight that I would rather fight is one in which I have overwhelming odds of winning.
Monkey bite your face off
> An adult male cannot physically take on a monkey.

Really? I would expect that the inevitable injuries aren't worth it, but I'd expect this to be the case on both sides, with the monkey ending up significantly worse off if the human were to actually consider it a fight-to-kill-or-be-killed, not a "make the nuisance go away".

What I don't understand though: If the monkeys are such a nuisance, why are they tolerated? Is there a religious taboo against hurting them? Legal protection? Strict limits on what kind of weapons people can have?

yes, i'd say there is both societal taboo (especially outright culling them rather than just throwing stones at them to chase them away) and legal restrictions: https://www.nytimes.com/2012/05/23/world/asia/fed-by-indians...

I would say that at least in north east india, monkeys didn't seem to be a huge problem. There are langurs everywhere, but they mostly stick to trees or the jungle, or sometimes the outskirts of towns. I think it's probably because they have plenty of places to eat there relative to the more urbanized parts of the country.

Religious taboo is held by some of the Indians. Not all or even most of them.

A religious granny wouldn't want to kill a monkey, but if her grandson is threatened? Hell yes.

And, yes, they are protected by wildlife conservation laws.

If slingshots are used, would a pellet gun be effective? They are inexpensive and can be fairly powerful. (Some pellet guns propel metal projectiles at speeds around 1,000 fps, which can be fatal to a human if incredibly well placed.)
Pellet guns would be illegal.

These monkeys are protected by wildlife conservation act.

Some weeks back, some guy poisoned a few pigeons that ate his crops that were being dried in the sun.

Last I heard that the police lodged a criminal case against him.

It was on the newspapers.

This world of ours has a tendency to evade equilibria
As a side note, I've read that polar bears are one of the most fearless animal towards humans because they had so little interactions with us.
And if they knew what we were doing to their environment boy would they be pissed!
indian kids throw rocks on dogs and monkeys when walking home from school to let off steam. i've personally seen a dog go after the kids for it. same with monkeys
Yeah I don't think the GP is correct, langoors are more passive and mostly mind their own business (at least in North India). Macaques are a menace everywhere.
Someone could crowdsource a documentary and launch their career with the money it would raise...
I've been reading Mary Roach's new book (Fuzz) that has an interesting chapter on monkeys in India. Because macaques are afraid of langurs, some people would tie up langurs outside their houses for security. This was eventually deemed inhumane but it probably still happens in wealthy enclaves. Nowadays the Parliament building is protected by 40 humans who imitate langurs.
I remember when I travelled in India there was a bus stop where monkeys had specialized on stealing food from women. They would leave men alone and only go after women’s backpacks. They were also really good at unscrewing the caps of water bottles.

Clever. At least the problem of your babies being killed by errant dogs (from the monkies' point of view) is solved.
If you are in doubt about this being revenge, because you think revenge is exclusively a human behavior, then have a look at the Gombe Chimpanzee War [0].

[0]: https://en.wikipedia.org/wiki/Gombe_Chimpanzee_War

People have this funny idea that war is a human invention and that nature would be peaceful and quiet without us.

But it turns out ants and termites have been at it for probably over 100 million years: https://www.wearethemighty.com/articles/why-ants-and-termite...

I think that some people have noticed that greater progress is made through cooperation which is why they gape their mouths when the people running the war machine buy an extra yacht for their great grandkids.
Well that's super interesting.

I'm wondering, what does the article mean by the 3 enslaved at the end? I'm not sure what that would mean in the context of chimps

The female apes were forcibly taken as new mates in the tribe.
I am still in doubt about this being revenge. I'm not necessarily saying it isn't, but doesn't culling the dogs as a means of pest control also fit the hypothesis? I mean, if a baby in a human town was bit by a rat, we humans would react by trying to eradicate the local rat population. You could call that revenge I guess, but normally we wouldn't ascribe such a passionate motive to our behavior, we would say it was logical to eliminate a source of danger.
Logic and emotion need not be at odds. In fact, in a natural setting, emotions are almost always aligned with logical self preservation and advancement.
The only difference is that we’re capable of industrialising that effort.

Thinking otherwise is a mere extension of the Noble Savage.

It could be a way of demonstrating fitness to mate. And with less risk of injury to your own family.
In Singapore last week, an older man was taking a morning walk in a park and spotted a pack of otters on the path ahead of him. At the same time, a jogger ran through the pack and startled them (some reports said trampled one of the pups). The reaction of the pack was to attack the nearest human - the older man:

As the runner ran past Spencer and disappeared into the distance, the otters instead set their sights on Spencer and "went crazy".

"I didn't move quick enough and they just jumped me and they [were] on me and severely bit my ankle, made me buckle, and they jumped on my bottom and pushed me. And these things like... massive... [these] things [are] like dogs."

Spencer said that the otters even tried to bite his face, but their teeth sank into his finger instead when he raised his hands to defend himself.

https://mothership.sg/2021/12/otters-bite-man-botanic-garden... (Warning - graphic)

FYI, he ran into the path of a pack of otters during his morning run and that is the reason why he was “attacked”. It is very possible he stepped onto an otter while doing that too, which would explain their behaviour.

What is interesting is he lawyered up, fabricated a fantastical story and somehow got the attention of Western media, all to seek compensation from the park. (And how many people believed him)

Play stupid games, win stupid prizes. Think twice about running head-on into a pack of animals regardless of their size.

My comment is getting downvoted but I still stand by my opinion that otters are not inherently aggressive like how a lion or tiger is.

Extra care should be taken when dealing with wild animals, even if they look small and adorable. Running into a pack of wild animals is not something anyone should do.

Otters are relatives of weasels and badgers and like their relatives they are very aggressive.
I believe they are aggressive only to the extent of defending their territory or defending their pups.

In fact, all carnivorous animals can be aggressive. They are not aggressive like how a lion or tiger is to humans. Their main diet consist of fish, invertebrate and shellfish.

Having dived with pacific otters, they are just plain aggressive. They seemed to genuinely just enjoy being mean.

Sea lions, on the other hand, are super pleasant and playful.

Sea otters are known to be more aggressive than river otters but I do not think they view humans as preys. It is probably a territorial or mating reason in your case.

I have read different reports of what the OP mentioned. The official statement by the park is that he (as reported to them by himself) ran through the pack of otters because of poor visibility (early morning) and tried to get them to do something about the otters. That is quite different from what the OP claims.

This is interesting. Can you post links to these reports?
This site really has become india central. Holy shit.
Probably depends on which time zones are in daylight when you visit.
Don't know why people are so reluctant to admit animals are highly developed intellectualy. The cocncept of revenge is usually just denied, despite common observations. Wild animals, mostly, of course. Ask farmers - they'll have one or two stories of crows taking revenge. Even on humans.
The people commenting on the Newsweek page were saying exactly this, that there was a simpler instinctual mechanism to describe the monkey's behavior. Who knows why.
This is the most interesting part:

"We've seen that when an individual is attacked in some way, the likelihood of them attacking someone related to their aggressor is higher," Poindexter told Gizmodo. "Typically there's a preference for attacking a third-party associated with the original aggressor, as opposed to the actual aggressor...for the most part, these acts of 'revenge' take place shortly after the attack."

Poindexter also explained that groups of hyenas have been known to seek revenge on the aggressor's relatives instead of the actual aggressor.

I mean based on their intelligent behaviour it wouldn't be surprising to find out that they feel emotions like love towards their offspring (even if not necessarily in the exact same way as us) and they know how one feels at the loss of a loved one. So by extension, if they want to cause the greatest hurt to the opponent, hurting their loved ones would be quite effective.
This is a gem for Karl Pilkington, true monkey news!
Great. Get the cats next
> But when officials attempted to catch the monkeys, they were unable to capture a single monkey.

Sounds like they're in cahoots

So I'm guessing that without intervention, two distinct sentient groups would be at constant warfare with each other until one group was extinct.

Is this what happened with early hominids and why there aren't other creatures that have evolved to the same level of intelligence as humans?

Eating diets rich in fat was key for early hominid brain development. Probably why other creatures haven’t evolved to our levels of intelligence.
GP referred to other hominids. I'm pretty sure Neanderthals liked eating fat too.
Even if you fight, you cannot win.
I'm confident humans will always win against monkeys. It's just not worth the effort at first. But when the situation escalates, like it seems to be when infants are at risk, those monkeys will eventually be captured or killed off.
