From NYRB December 14th 2016
The concept of evil has fallen out of favor in our disenchanted world. Its religious and superstitious connotations are permissible in horror movies, but otherwise often deemed embarrassing. Without some religious metaphysics it is hard to make sense of the idea that there are people who are intrinsically evil; it no longer seems plausible to many of us that people can be motivated by something that can be described as pure evil. Sustained cruelty is therefore often explained as sociopathy (the slick, psychopathic killers beloved of Hollywood), or a personality disorder stemming from some deep personal or social injury, or as some horribly warped conception of what is good. Even in the case of a mass murderer on the order of Joseph Stalin it has become part of his legend that he was emotionally scarred by having been a weak and sickly child with a brutally abusive father.
