Le warhammer

It's weird how religionstrags get defensive about the 40k Emperor's atheism when the man himself says he's not a real god and never wanted people to worship them because that's how you get unbeatably powerful warp demon entities calling themselves god in the first place.

In the end he finds himself getting turned into a god against his will as his empire plunges further into degeneracy and decline, creating this living nightmare of a feedback loop for him. And he still wouldn't be an omnipotent god like Yaweh or whatever.

And worst of all, he's actually a Turk! They want to worship a Turk!
