Now that I've said that, I realize how the Drow/Dark Elves in FR and I assume in similar works of fiction differ from many of the suggest similar cultures in this thread. While every society has its exceptions which makes the entirety of it either morally neutral or good, the Dark Elves/Drow are on a whole evil, there is no grey area with them They like doing everything that you were taught is wrong to do. They relish in it, and that's the thing. Orzammar has its politics and backstabbing, but that's just usually them seeking out justice through means that best suit them in some cases. A powerful Dwarven Noble whose honor was besmirched by some lesser noble would kill or disgrace the lesser noble or vice versa, by Drow comparison, that's child's play. They'd be plotting for centuries waiting for the perfect moment to raze your entire house/clan to the ground, enslave the strong, kill the weak, and eat the babies. (I'm not kidding either.) This would be a cool event to by every other citizen in the city, like a new years festival, they'd be secretly revelling in it. Then at the end of it all should it go well, they'd praise their evil spider goddess for her favor and hope she enjoyed all their wickedness.
