I really think people blow this crying about Orcs out of proportion, there was NEVER an actually interesting villain in this game whose reasons of being a villain boil down only to "I'm an Orc, Goblin, Drow or other evil race". And saying a whole species is inherently evil effectively diminishes all evil they do because you are saying they never could choose not to do it, which reduces them to children who don't know better. People should move on and stop flooding my yt feed with identical videos repeating the same points.
In that case, however, Drow are the descendants of elves that followed a god that betrayed Corellon. They aren't innately evil, they are innately good/chaotic and programmed to be evil/lawful (by DND logic).
Orcs are theoretically opposite. Evil/chaotic by essentialist, divinely mandated nature and capable of learning otherwise.
More importantly, they're people the PCs can murder for gold with no discussion about morality... And while that's convenient for some DMs it does have some very, very obvious problems.
