A conscience is, for a while anyway, pretty easy to fake.

The central trait of sociopathy is a complete lack of conscience, which is very difficult for most people to get their heads around, because those of us who do have a conscience can't really imagine what it would be like if we didn't. Most people think that deep down everybody has a conscience, and it turns out that's just not true.

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.

Sociopaths love power. They love winning. If you take loving kindness out of the human brain, there's not much left except the will to win.

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.

Being sociopath is not what most people would consider to be winning. Most of us have some kind of positive goal in mind when we think of winning. A sociopath thinks in terms of successfully manipulating someone into doing something that he or she would not have done otherwise. That can be a small thing or a tremendous thing, but the point for the sociopath is to win, to make sure that this person does what they're trying to coerce him or her into doing. It can be as disgusting and as simple as making a child cry. Or it can be as complex as making your wife feel bad about herself.

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.
