"There's a very specific formula for creating a monster. It starts with chronic, unrelenting abuse. There's got to be societal notification and then passing on. The child eventually believes that what's being done is societally sanctioned. And after a while, empathy – which we have to learn, we're not born with it – cracks and dies. He feels only his own pain. There's your predatory sociopath.""
