You don't have to "approve" or "condemn" anyone in order to recognise that, realistically, if you're in the society that this image came from, you can't be surprised if the people whose houses you bombed while cheering would probably not treat you well when they got out from behind the prison wall.

You can say it's morally bad and wrong and, ok, but also, what do you expect guys? The risk you run, when you're an oppressor class of any kind, is that the people you're oppressing murder you and your family in your beds. Play the game by the rules or not at all.
