Stupid question, it would be negative ROI as electricity costs eclipse BTC value
Correct answer, but bad tone. From https://news.ycombinator.com/newsguidelines.html

Somewhat related: If someone steals your Amazon credentials, he can use them to mine bitcoins. Using the CPU to mine bitcoin is not efficient and the value of the mined bitcoins will be much smaller that the cost of electricity and Amazon services, but it doesn't mater because he is not paying the bill. For example read: http://www.securityweek.com/how-hackers-target-cloud-service...

PS: It may be a interesting to know this as a theoretical question. But as a practical question, the idea is not profitable at all.

Definitely not meant to be interpreted as a practical question. Just a theoretical "what if" kind of question.
Probably enough to do a 51% attack on the bitcoin network and convert all bitcoins to amazon coins
Do you have any figures to back that up? My assumption would be that all of amazon would be a drop in the bucket for bitcoin mining. Their hardware isn't designed for SHA-256 hashing, so unless they had dedicated ASIC's my assumption is that they wouldn't even be close. Be interesting to find out for sure if someone knows though.

Just as an aside, even if you had 100% of mining you couldn't spend peoples coins. You could stop people spending their coins, but miners can't modify existing transactions, just not include new transactions in blocks they mine.
