The truth is that when you kill a man it doesn't matter if he's your enemy and if he's trying to kill you. That moment of his death will eat at you for the rest of your life. It'll dig into bone so deep inside you that not even the hand of God is going to be able to pull it out, I don't care how much you pray. And you multiply that feeling by several years and too many doomed engagements and more horror, Frankie, than you can possibly imagine. And the utter senselessness and the total hopelessness become your enemy as much as any man pointing a rifle at you.
