@Elandra77: Betraying Balgruuf ( and Whiterun ) is the part I hate the most about going Stormcloak.
If there was a Balgruuf side I would gladly side with it, but as for now... Stormcloaks.
Ulfric's cause is fair, but him as a character is meh...His a good speaker, but when you see past his beautiful speeches and play the game long enough, you get that he's there for power...For what he believe in too, but for power. Then again, everyone wants Power, so whatever. That, and the fact that he's a racist, for good reasons, but still racist.
But the cause is just and fair, and there would've been a rebellion if there wasn't oppression in the first place.
The Empire is ugh...Even taking into consideration that they are trying to postpone the confrontation with the Thalmors until they gain enough power, which makes their decisions kinda logical...I just can't stand how they welcomed them, letting them kill/torture Talos worshippers. A bunch of cowards afraid to take actions...
Both sides are equal. But my backstory fits the stormcloaks.
Fun fact: I don't even play as a Nord XD
