I have recently read Ted Chiang's short story "Hell is the absence of God" and I think "what if religion were real, and that is immensely scary" is going to be one of my new favorite nieches.
Any other books/novellas with this premise (other pieces of media too if they come up, I don't mind) or a similar vibe to it?
I have already read A short stay in hell by Peck (I know this is going to be an obvious suggestion)
