Humor, jokes, memes about TTRPGs
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.
Your game, your rules. That's the beauty of it. I make everything up as I go along.
Deekin is a great example of how an evil species (Lawful Evil Kobold) can make a great narrative.
I don't think you necessarily need to have a whole species be one alignment for it.
Just having the culture of a specific community aligned a certain way (ideally with a reason) is more interesting than "all x do bad stuff because they're bad and they like badness."
Mindflayers are definitly evil (from humanoid perstective) because of their species. They eat and bread brains. And they are interesting.
