I also completely support her methods of increasing her people's numbers. I love that instead of waking up as a not-mindless undead has been replaced by being called up by a Val'kyr if you decide to roll Forsaken. And her little exchange with Garrosh in Silverpine Forest is priceless.
Yes, she's going on with the plague behind everyone's back, and that's a bad thing. But she has the Forsaken's best interests at heart, as desiccated as that heart may be. I wouldn't want her to become leader of the Horde though. She's much more fun where she is.
