" The truth is, Rosemary, that you are capable of anything. Good or bad. You always have been, and you always will be. Given the right push, you, too, could do horrible things. That darkness exists within all of us. You think every soldier who picked up a cutter gun was a bad person? No. She was just doing what the soldier next to her was doing, who was doing what the soldier next to her was doing, and so on and so on. And I bet most of them — not all, but most — who made it through the war spent a long time after trying to understand what they’d done. Wondering how they ever could have done it in the first place. Wondering when killing became so comfortable. "
