The Empire are nothing but the puppets of the Thalmor, too weak to protect themselves, their people, and their faith.
Who can blame them for that? You said it yourself, they are too weak. What are they supposed to do, continue to fight the Thalmor and die right down to the last child? The choice to give in to the Thalmor was made for the greater good, and the greater good being thousands of innocent lives could be spared.
The corruption of the empire is seen immediatly when that Imperial Officer orders you to the headsman's block without mercy or consideration of your innocence.
I think it's rather presumptuous to say that the one imperial officer who ordered your execution is the sole embodiment of the entire empires way of doing things. As far as I'm concerned she's just some power tripping beotch. If you think that every Imperial reflects the core values of the empire, what of Hadvar? He's a great guy. Even Tullius isn't half bad "gaurds, get the townspeople to saftey..."
Standing with Ulfric and the Stormcloaks is the right decision because you are ultimatly overthrowing a corrupt empire in order to overthrow the tyranni of the Aldmeri Dominion and safeguarding Skyrim from oppression as Ysgramor did before you.
I agree on everything said here except for the "corrupt empire" part. I don't think they're corrupt, so much as they are doing all they can to avoid any more bloody conflicts. "the empire is going to put you down,
and restore the peace"
Ulfric Stormcloak killed Toryg in fair combat. Toryg could have declined the dual and stepped down from the throw if he chose it. Rogvir was still executed to opening the door for Ulfric even though niether Ulfric nor Rogvir committed a crime.
Somebody correct me if I'm wrong, but I don't think what happened between Torygg and Ulfric is completely known, and whoever tells one side is heavily biased.
In conclusion, supporting the Stormcloaks is not treason. How can it be treason when the Thalmor(and the twisted remnants of the Empire) are not sovereign over Skyrim?
Well, Skyrim is a part of the empire and is subject to its laws, and as it happened the signing of the WGC allowed Thalmor to roam freely throughout the land, purging those who defied their rules.
But all that being said, I take the Stormcloaks side, just because the Imperials are too much like "The Man", you know? Nobody likes (or should like) The Man. I make these points because I'm just passing time waiting for my Louis CK video to finish downloading.
