Sure, but it became a lot more on the nose post Cata, and that's without mentioning the endless debates around said free will which is a can of worms I refuse to open here. Plus Sylvanas and the Forsaken had somewhat sympathetic motives in the form of taking vengeance upon Arthas, whereas after his death they (and, especially, her) basically commit all these atrocities for their own benefit.
That's not to say every playable faction or character has to be sympathetic of course. But I also think both the race and its leader steadily lost any of their potential depths to just become the Horde's resident assholes who do asshole things.
