" Then let me tell you something instead. When they make an Envoy, do you want to know what they do? They burn out every evolved violence limitation instinct in the human psyche. Submission signal recognition, pecking-order dynamics, pack loyalties. It all goes, tuned out a neuron at a time; and they replace it with a conscious will to harm.” He stared back at me in silence. “Do you understand me? It would have been easier to kill you just then. It would have been easier. I had to stop myself. That’s what an Envoy is, Curtis. A reassembled human. An artifice. "
