I don't know a lot about the source really, but I do know that article is undoubtedly not even coming close to showing the worst of it. It certainly is a heavy subject. It is so maddening that these people blend in the way they do and that it takes so much disgusting digging to root them out.

Following their trail, and understanding their thinking is pretty depressing. Psychopaths don't think like we do though. Its like if the whole world outside your own head seemed like a big game to you, and the only purpose of that world was to serve you. That sort of insane narcissism is hard to relate to, and the devastation it inflicts is just vile. That the very most evil in this world have such reach and control and support is aggravating. We need to develop systems and methods for identifying psychopathic behavior and treating or isolating those who exhibit it. We mostly just need to stop rewarding it so much, and with such blind eyes and a half-hearted interest in the truth.
