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.
Evil races give someone the PCs don't have to feel bad about killing. Obviously depends on your party, but if they befriend the hungry wolf pack and negotiate with the bandits, then a band of definitely evil goblins gives the barbarian something to smash without worrying if they're killing little Timmy's dad.
Edited to add: And if "he's an evil race" is your only reason for them being a major villain, that's bad storytelling. About as bad as "yes they're going to help you because they're good," and not for some kind of benefit to them, monetary or spiritual or whatever.
Eh, but maybe the barbarian should have to think about whether smash is the right path forward?
Also, you can have an individual group of enemies who are very clearly definitely evil without needing to relegate an entire species to it.
That said I run campaigns which are pretty far removed from my players wanting to smash dudes without a second thought.
Except the bard, right?
Ayyyyy
