Every time people lament changes to the lore that amount to “not every member of species X is irredeemably evil” and claim the game is removing villains from it, I think how villains of so-caleld evil species fall into two cathegories: a) bland and boring and b)have something else, unrelated to their species going on for them, that makes them interesting.
I dunno, when you literally have spells that detect or harm specific alignments, it makes good/evil more fundamental than in the real world, and that’s fine for a fantasy world IMO.
