The difference between sociopath and psychopath is, I believe, settling in on the idea that psychopaths are born and sociopaths are made through environmental factors.

The case of James Fallon is, to me, very interesting reading, and watching on YouTube. This is a person who is as different from me in their general orientation toward social life as a gay person is in their sexual orientation. A person who can lie and manipulate without a feeling of guilt. I would need to understand that if I were to have anything to do with him! But I'm careful in business relationships anyway. Yes, he cognitively knows what might get him into social trouble and tends not to do those things. And doesn't need to, apparently, to get most of what he wants and needs from life.
