" I didn’t say anything because I didn’t have anything good to say. Just lately I had noticed that I could kill people and not blink. No attack of conscience, no nightmares, nothing. It was like some part of me had turned off. It didn’t bother me that I was able to kill so easily. It did bother me that it didn’t bother me. But it had its uses, like tonight. I think every last furry one of them had believed I’d do it. Sometimes, it was good to be scary. "
