Pure Evils who immensely enjoy watching their victims suffer. It by no means automatically entails them to also be Psychopaths. While the two have clear similarities and very often overlap, one still must address the staunch differences. They should also not be confused with Sadomasochists. While both are sadistic, Sadists only enjoy hurting others; while Sadomasochists enjoy hurting themselves as much as their victims.

Just because a villains is Pure Evil doesn't automatically mean they are sadistic, as some of them can be completely indifferent about other's suffering (e.g. Hans Gruber, Shou Tucker, Rip Blazkowicz, Kenjaku, Paradox, Bob Barnes, Decagrammaton, Ego, Sebastian Shaw, Lord Cutler Beckett and Harry Lime).
