Arnold is a harsh person on the outside and inside, not really caring about who he upsets. He isn't the type to fake it, he's just what he is. His talent is the Ultimate Leader, simply because he can keep people in line if he wants to. Within the game, though? Not at all. He doesn't want to. The more chaos, the better, simply because it keeps him safe, in the long run. If people leave him alone, they're less likely to do him harm. Of course, he does enjoy playing mind games with those who won't get it, but that leaves him open to them, himself.
