With all of the intergalactic wars that have occurred in the Marvel Universe, I'm surprised that not once did the Kree Empire had experience a conflict within themselves. From what I've heard, the Kree are a bunch of militiartistic and imperialistic warmongers. I'm inclined to believe that there are Kree who feel oppressed by the Empire's current regime, but out of fear of retaliation, they couldn't or wouldn't say anything.
If he were still alive, I'd like to think that Mar-Vell would've led a uprising against the forces of the Supreme Intelligence, Ronan the Accuser, and the entire Kree military. It'd also make for a for an interesting company-wide crossover, don't you think? Maybe the Avengers, Fantastic Four and the Guardians of the Galaxy get involve, considering their connections to the Kree.
