Anyway, it's not that he has nothing to loose. It's not that he's a monster either - he was, but he genuinely isn't. He could have left with the kid and the money. Or just with the money. He didn't. He got mad, and he revenged his friend. And then, spent, he left to raise his children. This is the point. The film is about deep shades of grey in classic western charactors. There are no monsters, just men.
