Well, they never show the Empire doing anything evil until they are provoked by the Rebel Alliance. I don't think they ever justified the rebellion, heck they don't even really mention why they are fighting the government in Star Wars. So I'd have to say stormtrooper.
But in spirit, I am a rebel. The nations I am descended from have both fought huge empires in the past, in fact the Romans never conquered us and we were the last to have Christianity imposed on us. And I believe very strongly in the importance of personal and political freedom.
