So, in one of my stories there's a cult dedicated to stopping an "evil" god coming to Earth and causing mayhem and all that. But what I want to happen in the story is for the god to actually come to Earth, only to just be some chill dude who just wants to hang out on Earth for a bit. One of my main characters had their life dedicated to this god, having killed people in the process.

So, basically, if this god were to come to Earth and just be chill and not cause mayhem, with the particular main character being distraught that the thing they were practically worshipping and killing for their whole life wasn't that big of a deal at all: would the reader most likely feel cheated in a way? Would it just be shit writing, is what I'm trying to ask.
