I just don't think society can function that way. If people can't trust each other, if numbers don't add up, that puts society on a very shaky basis, makes it impredictable and impossible to control.
BUT if we consider how that same person would probably feel if someone were to, say, come up to him/her and just rob them of everything they had, they wouldn't like it either. And bottom line is, it's not that some necessarily want to be doing what they're doing. But like I said, it's a very complicated issue, and sometimes you just don't have a choice. And then you can also look at this way: in every society where there are, in fact, rules, there also HAVE to be certain people who try to break them. Because if no one tried to break the rules, what would be the point of even having them in place? You understand what I'm trying to say?
