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.
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.
