Yeah, I was just kidding. My lust for vengeance ended when I planted my axe in the skull of Little Ms. Queen of Hearts. The only time I followed a Stormcloack was in the bigginning and it was just so I got to kill her.
I don't mind a little moral ambiguity. What I don't like are the quests that only offer evil options. Screw additional content. I had to kill the Dark Brotherhood and I can't stand the fact that I can't righteously rid Riften of the curse that is the Black Briars.
