Pure Evil

The darkest evil.

A form of evil that's the absolute most malicious of any kind of wickedness. As such, considering a person, act, or way of thinking Pure Evil is to say that there is no way anything or anyone can be worse than the subject of the remark. Many antagonist roles, such as the Jerkass, Overkill Villain, and SMCE Villain, vie to be the living definition of Pure Evil.
