It isn’t for no reason that psychopaths are often described as ‘evil,’ by people who would not attempt to understand them psychologically, for they do not exhibit the same disorganization of thought, and inability to adapt socially, that those who suffer from more visible signs of mental illness do exhibit (and which mitigates the culpability of those people, for actions whose consequences they might otherwise be responsible for). And so the deeds of the psychopath that earn him the designation by which we know him tend to assume a malevolence that we associate with scheming and duplicity. And rightly so, I think, for his crimes are premeditated, and are designed to exact for him an amount of satisfaction that is proportionate to, and arises out of, his victim’s pain. Though to describe such an individual as ‘evil’ is not quite correct, for evil is a spirit, and can only be channeled, or manifested, just as a person cannot really be ‘good’, but can only channel or manifest ‘goodness.’
