Yeah, I don't think enough writers draw attention to how many superheroes are basically horror monsters picking off henchmen from the shadows.

Apparently that's become part of some of the recent Batman video games but I assume that's not from the villain's perspective.

Suddenly realizing your gang has vanished and then seeing your terrified face reflected in Spider-Man's giant eyes is scary enough. The only thing worse than only seeing Nightcrawler's eyes and teeth before he jumps you is getting a clear look at him.
