" If only there were evil people somewhere insidiously committing evil deeds, and it were necessary only to separate them from the rest of us and destroy them. But the line dividing good and evil cuts through the heart of every human being. And who is willing to destroy a piece of his own heart?” I also love the way Joyce Carol Oates puts it: “To examine the mind of the serial killer is to examine the human mind in extremis, and should anything ‘human’ be alien to us? Where the ‘human’ crosses over into the ‘monstrous’ is after all a matter of law, theology, or aesthetic taste. "
