Alright, this is going to clear up some confusion about the Empire. For one, they were never the "good guys" like so many wrongfully claim. THE EMPIRE INVADED ALL OF THE PROVINCES OF TAMRIEL, THEY WERE NEVER PROVOKED! So what if the Empire outlawed slavery, they still allowed it in Morrowind, conquered and killed many innocent people when taking all the provinces, levied huge taxes on wealth and people (to form new legions). The Imperials never had any sort of claim to any of the territory that they took over. So why do people see them as the good guys? There are several in-game books at the time of Oblivion that question just why the hell does the Empire try and hold onto some of the more far-flung provinces. Elsweyr for example has been in practically open rebellion with the Renrijra Krin...
So, now we are in the time of Skyrim and for once I believe BGS is rightfully portraying the Empire-as corrupt Romans that are desperately trying to hold onto illgotten gains. The Stormcloaks are no saints themselves either, just to clear that up. So please stop saying that the Empire are the good guys, far from it.
