When you first go to see Ulfric he makes this emotional speech about why he is fighting.
His speech is almost convincing, almost.
So I had this character join the Stormcloaks and go through the civil war questline.
At the end of the questline when Ulfric takes Solitude, he shows his true colors.
Through the things that he says behind the scenes to the Dragonsborn and Galmor, you can see that he didn't start the war for his people or for what they wanted, but he started the war all for himself.
I'm now fully convinced that the Imperials are the right side to go with.
I even noticed that the Imperials treat you much better than the Stormcloaks.
