You use the term "Power-hungry" like if its a bad thing. In fact that that is very typical for a politician so don't dangle that word to discredit Ulfric. The Emperor surrendered free worship to continue his status as Emperor, guess who was power hungry at the time
Don't you realize just how weak the Empire is? For a General to surrender under pressure just as Ulfric and Galmar enters Castle Dour and hides behind a woman, and then the actual Emperor gets assassinated by the Dark Brotherhood due to crappy and weak security. Yeah The empire can definitely handle the Dominion on round 2.
