I'm a fan of the series "Through the Wormhole with Morgan Freeman." One of the episodes I have on my DVR right now is "Can We Eliminate Evil?"
It was a particularly well-done episode that discusses human behavior and the human brain, with regard to evil and psychopathy. It even wanders into socialism (without saying so) and fascism (without pointing a finger at the US.) It ends with positive notes about violence decreasing. A researcher actually used cooperation and violence in the same sentence. What's cool about that is that it wasn't stated in the context of government coercion being a positive, but the implication seemed to be there that it was a negative (though he did refer to "the rule of law" as a positive, which seems to be an interesting point of discussion amongst self-described libertarians.) I found the show fascinating.

After I posted that, I saw the very end, the closing by Morgan Freeman. It disturbingly referenced, positively, the possibility of identifying people prone to violence and "stopping them" before they do evil, which I still consider an evil concept, regardless of what we supposedly "know."
