Antagonists ≠ villains.

Antagonist = people who oppose the main character (the protagonist) of a story.

Villains = people in a story who are morally in the wrong.

Antagonists can be villains, and they tend to be. But villains can also be protagonists (for example, Macbeth.)

The "antagonist" category is for characters who are destined to be antagonists in their story. The "villain" category can be used for characters who are the antagonist & a villain, or characters villainous in their own right.
