Awesome movie though, right? I kind of got the idea that the hero (villain) had an attack of conscience, just wanted to do one good thing, and once he started it was too late to stop. Maybe he thought of his own father as a failure, or a weak man and remembered how much that hurt, or realized that was what ruined his life. maybe he saw that it was too late for his own redemption but this boy had a chance if he could just look up to his father.
I don't know. Good movie though.
