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.
Big cats have hunting instincts that are hard to turn off even if they like you (see: any news story of a big cat eating their owner), humans have instincts relating to forming communities. every single species has some instincts they follow and they aren't the same as ours, they'll deeply shape how a species' cultures/morals/etc develop. Just saying goblins are little green humans is deeply boring and hurts world building.
