Look at this scenario:

We know that the USA is the current epicenter of Western Civilization, the force keeping the Greek and Roman myths alive. Say this American citizen suddenly died, they're automatically destined for the Underworld, whether this person believes in the Abrahamic afterlife or not. Remember, we don't have evidence that suggests Heaven and Hell is even real in PJO/HoO. I believe Percy and Grover touched on this in The Lightning Thief.

Now, say this same person was for some reason given Egyptian funerary rites instead, they would then go to the Land of the Dead because that's the afterlife the soul was prepared for. Same logic applies to the Norse afterlife. If the deceased was given Norse funerary rites, they go to the Norse afterlife even if the person in question was Christian, Greek, or atheist. That's how it seems to work in the Riordanverse at least.
