Obi-wan... he's a Jedi Knight who had his fellows hunted down and killed by his pupil and the Empire. He's going to have negative opinions about the Empire. Obi-wan does not give a reason why the Empire or his pupil killed the Jedi, just that they did. So Obi-wan's opinion is biased and cannot be viewed as truth like an outsider's opinion could. Luke... he lives on the Outer Rim on a world harboring a criminal warlord with no Imperial presence before ANH. So he has good reason to hate the Empire, that does not mean the Empire is evil. It just means the Empire's influence either a) doesn't reach Tatooine (which it probably doesnt since the OR didnt reach it in PT) or b) Tatooine is too insignificant of a world to even bother with. Again like before Luke doesn't give his reasons why he hates the Empire. He just says he does but if you look at his surroundings you can see why he would. As for the Mofference on the DS, I never saw them (except Vader and Tarkin) as evil. I saw the officers as arrogant military officers with a new toy. Just like all Generals and Admirals tend to act like when they get a nice big boom stick to play with. On the Outer Rim where the Empire's influence is very little and the worlds and the people can do whatever they want, I can imagine the locals would hate the Empire if a criminal warlord was in control or ran free all over the place. And when the Empire exerted its influence in the Outer Rim I can imagine those people who were use to not having that presence are going to feel violated, oppressed, offended. Just like with any government that doesn't pay attention to its people for a long time and then suddenly does is going to be hated by some or loved by others. So out in the Outer Rim thats your mindset based on what we see with Tatooine in ANH. That is, however, not what the mindset is going to be for the galaxy as a whole. So yes, its a minorities point of view for now.
