she literally say she is trying to keep the horde alive, after less than 5 min of nuking the horde with plague and then raise their corpses as skeletons
Even the Lich King cared for his troops more than her, yes seriously the Lich King showed more care for his sentient followers than her
If Sarufang betrayed the horde, Sylvanas didn't even give a f8ck about the horde ever any day, and joined the horde with treachery and manipulation, with quests (that were removed sadly later) showing how she was planning something with Grimtotem in first place
In case u forgot, Baine is why Forsaken joined the horde after persuade Thrall, and he did that only under constant pursuing from Grimtotem, who lorewise are horde, even if for gameplay purpose they were hostile to us
