Villain

A villain is a Bad Guy. Villains generally do Bad Things to Good People, and occassionally to Bad People, too.

Depending on their degree of evil, villains may commit a variety of crimes from the petty to the disgusting. A few follow some sort of code of honour, while others are completely without morals, and some are intelligent - perhaps to the point of being geniuses - while others are terminally stupid.

Compare with hero.
