Antagonist: a person who actively opposes or is hostile to someone or something; an adversary.

Grimm are wild animals, and evil force, not people. It's like saying the generic posonality-less robots in Sonic are antagonists, they're not. They're just a force being used by an antagonist, Dr Robotnik. Same case here just with Salem.
