While it’s not quite the same as some dude using his diety-granted powers for something more trivial. There are certainly cases of deity granted villians, in both DC and Marvel.
Juggernaut for instance, isn’t a mutant, but a guy empowered by a deity named Cyttorak:
And Black Adam is an Ancient Egyptian predecessor of Captain Marvel granted the attributed powers of a set of Egyptian deities. (Here SHAZAM is both a wizard who grants Captain Marvel’s powers but also an acronym for the specific deities being called upon. Because of some trickery Black Adam’s powers are directly from the Egyptian dieties, while Captain Marvel’s are via the wizard and Greek derived)
I’m positive there are more examples, but these two are the biggest that come immediately to mind.
