Most of us fill up our lives and end our boredom with our involvement with other people - people we love, people we hate, people we're afraid of, people we're interested in - and that's what keeps our minds going. So if you're sociopathic and you really have no caring for anybody, there's not much left, only boredom, and the way to relieve that, apparently, is to play a game and make sure that you win.

If you don't have a conscience, what is your behavior like? Apparently, if you don't have a conscience, if you don't really . . . love, then the only thing that's left for you is the game - it's about controlling things.

Sociopaths differ fairly dramatically in how their brains react to emotional words. An emotional word is love, hate, anger, mom, death, anything that we associate with an emotional reaction. We are wired to process those words more readily than neutral, nonemotional words. We are very emotional creatures. But sociopaths listen as evenly to emotional words as they do to lamp or book - there's no neurological difference.

Sociopaths are not usually physically violent. A typical sociopath never kills anybody and doesn't look like Charles Manson - they look like you and me and everybody else. You're not looking for someone who's recognizably evil or scary-looking, but rather someone who looks normal. Another lynchpin is dishonesty. Lying for the sake of lying. Lying just to see whether you can trick people. And sometimes telling larger lies to get larger effects.

When you were a child, where boredom could actually get to be painful. Sociopaths experience that kind of pain in boredom. And so to be alone, to have nobody to play the game with, can be painful. It's not exactly fear, it's a kind of pain.

When I speak of divisions greater than gender or race, I say that because it is so unimaginable. I can imagine what it would be like to be another race. Or to be a man - I could draw that up in my mind and experience it. Schizophrenia? We're all schizophrenic in our dreams. Depression? Most of us have been at least a little depressed and can imagine it. But not having a conscience? Conscience is so profound and so basic in most of us.

Sociopathy is the inability to process emotional experience, including love and caring, except when such experience can be calculated as a coldly intellectual task.
