Drow are no longer evil and have embraced neo-liberal dogma
I think that there's a difference between people being inherently evil as in genetically evil and culturally evil.
The Drow are clearly culturally evil even in the game, that doesn't mean that every single Drow is.
Just like how just because America has a culture that glorifies violence and is full of religious fundamentalists doesn't mean that every American fantasise about being Charles Bronson in Death Wish and hates gay people.
