And, because turnabout is fair play, I am now considering what would happen if you opened up demons and devils and other fiends to a similar unaligned status. How would that work? It has potential; you certainly get more of the "screaming monstrosity which introduces itself by saying BE NOT AFRAID" feel. And it also further breaks up the "Team Good vs Team Evil" concept where morality is just a hat you wear to a fight, because you can have devilish torturers serving a deity of mercy and forgiveness, so long as they're working to redeem their wards or otherwise serve the overall values of their deity. I'm pretty sure old-school Crom sent out devils if you prayed to him, for example.
