Hackers are not all bad some of them act this way as Robinhood does. but this isn't right at all because, in this way, there will be some people who suffer, and stealing is not really the best way to help those in need quickly. Just like what happened to this guy here, when he got caught he paid for his sin with his life but overall he is happy about his ending. I don't know if it is true or not but such kind of hacker might exist out there.
