Not to the same extent. I don’t think Anduin’s body count is anywhere near as comparable as Sylvanas’s.
We’re sort of getting off track here. We’re arguing over the morality of Sylvanas’s actions when my initial point was that it’s totally unnecessary. Warcraft has allowed us to support someone as abhorrent as Arthas in the RTS series. Desiring to support Sylvanas, regardless of how you see her, should not be considered taboo. It’s just that most of the arguments I see in favor of her seem to take it upon themselves to whitewash her first before announcing their support. I feel that is also unnecessary. Even if she were overtly the worst mass murder in WoW history it would be ok to say you support her. It’s all just a video game, after all.
