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.

The reason I want to explain that you're probably never going to get revenge a sociopath and you're also probably not going to redeem this person, is that it is not a project that will ever succeed. At present, if a person does not have a conscience, we know of no way to instill one - not even a little bit. It's not like something you can take off the shelf and put into somebody's brain. It makes me so sad to hear people say, "I think I can see just a little bit of a conscience."

Sociopaths are not afraid of very much, except for physical harm and dying - really primitive, basic kinds of fears. The problem with being alone for a sociopath is boredom.

One way or another, a life without conscience is a failed life.

Most of who we are is our deepest emotions, and someone who cannot feel those emotions in a positive way is never going to understand much about his fellow human beings.

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.

An intelligent sociopath can learn the rules about what's good and what's bad, what people see as good and bad. But they don't get that intervening sense of guilt, that pang of conscience, on account of it. So they tend to know what's wrong or right, they just don't care. That's another thing that they can use against us: that we do care. We're predictable in that.
