Not exactly wrathful, more like, he shows up when there's a lot of ambient wrath going on. Mainly he just resurrects all who died in faith and sets up a judgment throne.

And he won't kill them, just they don't get heaven. The sheep and goats judgment. The section that "What you have done to the least of those, you have done to me" comes from there.

Honestly I think the existential suffering brought about by realizing that they have no place in heaven after a lifetime of religious lip service is FAR more poignant than any death could be

Not that most lemmings think this is anything more than a long repeated fairy tale, granted
