Another thing that's fun for sociopath is speed, literal speed, going very fast in your car. Not that everybody who goes fast in their car is a sociopath, by any means, but anything that gives you a rush will lessen your sense of boredom.

People ask me many times, "Aren't you afraid you're going to scare people? Aren't you afraid you're going to make people feel bad about the human race?" I look at it as entirely the opposite. Something you can understand and identify should be less frightening than something you can't. And to understand that there are people who are capable of acting without conscience, without considering other people at all, explains a lot of things.

The most reliable sign, the most universal behavior of unscrupulous people is not directed, as one might imagine, at our fearfulness. It is, perversely, an appeal to our sympathy.

If you see somebody really pulling for your sympathy while at the same time hurting you intermittently, you should start to wonder. If somebody plays to your pity and really tries to draw that out of you, that's not normal.

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

The sociopath wants the person to be easily enough fooled to stick with him. This can be accomplished by looking for someone who is very, very loyal. Most of us consider loyalty to be a very positive trait - and it is a positive trait. But it also blinds people to some of the traits of the person they're loyal to.

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