However, for example lets start on my first visit to Windhelm I come across two drunk Nords harassing this Argonian. Any who I then come across Brunwulf Free-Winter - Hero of the Great War who is quite sensitive to the hardships facing the Argonians and Dunmer. He talks about how he is disappointed with Ulfric and how Ulfric only cares about himself and about the Nords. He also mentions that Ulfric is content to keep things the way they are in Windhelm.
Then on my way to Riften I come across Asger Snow-Shod. He has lost his sister in battle and feels very differently about Ulfirc. He took feels Ulfric is only bothered about Ulfric and no one else.
On the grander scale I personally see Skyrim falling to the hands of the Thalmor quicker with the Empire in charge. I mean Skyrim is the land of the free people. However, as much as I don't like Ulfric's actions I hate the Empire and the Thalmor even more.
I mean sure some of Ulfric's actions are noble and his cause is just. However, I just feel Ulfric is the lesser evil of the two. Even though I will probably side with the Stormcloaks since I believe everyone son and daughter of Skyrim should fight for their freedom, I am going to RP where I bring an end to the civil war and usurp Ulfric to the throne once all the matters in Skyrim (the DLCs have been released) have been settled.
Its probably been said before but I think someone like Ralof or Brunwulf Free-Winter would be better leaders of the rebellion. They both seem really nice people, especially Ralof who has the best for Skyrim in his heart.
