With no moral aversion to such behaviour, I had basically assumed all psychopaths would establish some kind of predatory behaviour in their lives. Manipulation, plagiarizing, discrediting, blackmailing, ect.
On one level, it's not surprising to me to see an outlier such as Mr. Fallon, but I can't shake it. When you have those tendencies as part of who you are, then the question really becomes "why didn't you act on them?" Oh your mother loved you a whole bunch? I see. The human spirit is just indomitable isn't it? Uh huh.
I suspect the simplest answer is: "he did."
It would raise my spirits to know that pro-social psychopaths exist. Seeing as the incidence of psychopathic symptoms on average is about 1/100 people. I've also learned not to believe something because I wish it to be true.
I fall on the nature side of the debate. It's a scary world.
