Usually sociopaths will look down upon us for that very reason - that we're gullible. We're weak. One person told me that he thought he was the only honest person because he would admit that he didn't have a conscience and everybody else was clearly faking it.

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.

The bottom line for most people who are normal is their need for other people. Even the greedy ones have this need - as long as they're not sociopathic. They may be very misguided and unhappy and do bad things and so forth, but in general if you look down deep, you find that these people are mainly concerned with other people and what other people think of them.

I was once doing a book signing and a man came up to me and said that he gave classes to people who'd been convicted of drunken driving twice. He said he felt that nearly all of those people were what I was describing as sociopathic. Which makes a great deal of sense to me. We always talk about how could you possibly, knowing that you're drunk, get behind the wheel of a car again and do that? Well, you could if you didn't give a half a damn what happened.

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.

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.
