Evil men in Mandos

[Rhun charioteer]

So when men die in Arda they go a separate hall than they elves and are basically processed and leave quickly going beyond the world. I'm curious what would happen in Mandos to evil men or men with evil cultures such as Melkor worship basically an easterling. Do they receive any sort of judgement? Or do the Valar simply pass men in and out of their doors without examining their moral and spiritual situation as they do elves?
