Because WE were at fault for beating up Illidan, who refused to tell us what his plans were. She took every chance she could to make it seem like it was OUR fault and that this is, literally, our quest for redemption. OUR. Redemption. Unless you play a Demon Hunter then she says "Oh, you're a demon hunter, my bad" after you go through the vision of Illidan in the Black Temple.
She's pretty Illidan's No.1 Fangirl.
