““Susan said. “You ought to not forget that whoever you killed last year, there were people you could have killed and didn’t.” “There’s that,” I said. “We all do what we need to, and what we have to, not what we ought to, or ought to have. You’re a violent man. You wouldn’t do your work if you weren’t. What makes you so attractive, among other things, is that your capacity for violence is never random, it is rarely self-indulgent, and you don’t take it lightly. You make mistakes. But they are mistakes of judgment. They are not mistakes of the heart.””
