"One of...oh, him." He giggled, surprised. "I hurt him? Really? God, I thought I was being nice. Would have been just as easy to kill him. Probably more fun, too. But you'd know that, right? Because you know my...type."
"Standards are just more rules," he said, suddenly deathly serious.."They restrict you and they tell you what to do but they don't improve you. Rules will never make you a different person. They just let you believe that you are."
He leaned back in his chair. "If you're a killer, then you're a killer. That's all there is to it. You can say you only kill a certain type but then you're already taking lives. What's the point of telling yourself not to at that point? Unless you think some people are worth more than everybody else. But that sounds like the type of thing that would mess with your...rules."
