The Villain Sucks

Even evil can be bad at what it's supposed to do.

This might be because Villain is a Joke Villain, The Jerkass, or some other UnTrash role that flounders in villainy. Their henchmen might get tired of their suck-ass failure at everything and quit the job. Hero might even call Villain pathetic. The worst thing that could happen to Villain is if the people they're suppose to intimidate laugh at them and don't feel threatened by them any longer.
