Dex turned around; Seth was staring in the lab, his face haggard. “Are you ever coming back?”
“Oh, I apologize, my darling. Were you waiting for me? Well, you know what I’m like.”
“Compulsive. Thorough.” Seth twisted his fingers together. “Disappointed.”
“What?”
“You have said it yourself,” Seth said. “The beast is only the man, stripped of the constraints of logic. You believe that, as a man, I will not commit murder, and that my conscience will keep a rein on my beast. But you know, there are many things that even a man might think, that a man might want, and because we think we’re civilized and domesticated and cowed, we won’t do. Haven’t you ever wanted to kill someone? Even over stupid things? A carriage driver who nearly runs you down in the street. A shopkeeper who mistakes your order. Do you ever just want to kill them, just throttle them, tear their throat out? It goes away. We don’t do it and it goes away.
