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.

If courage is acting according to one's conscience despite pain or fear, then strength is the ability to keep conscience awake and in force despite the demands of authorities to do otherwise.

People ask, "What could possibly cause a normal person to torture her own child?" Well, the answer is: Nothing could cause a normal person to torture their own child. The reason that we see that happening is that there are people who don't care, who don't love - even their own children.

Even famous people - are most concerned of all with what people who are close to them think. And the sociopath is generally not concerned with that at all.

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

Sociopaths are just like everybody else in that some of them are really brilliant, some of them are really stupid, and most of them are somewhere in between.
