I'm not criminal, but I do like guns, and think his life style is pretty cool, even if it is highly unhealty... but that is about it, guns is the only thing I can think of.
I don't have a bad attitude either, which he has and I love it. But maybe it is because I kind of play the game with him, even if he is just a bot... we do the same thing, kill zombies and work together, can that have an effect?
