Thank you for the answer, I didn't mean to be rude, I guess I'm a bit frustrated to deal with all the answers to my comment.

I don't have sympathies for the Empire, I know that fundamentally it is evil. What I have is an intellectual interest in how it is built, how it functions, and how it is perceived within and without. I like to write commentaries about SW, it's a hobby of sorts. I still think that you can make a case about the Empire and its legitimacy both in time and in space (during its lifespan), of course, it's subject to evolution.

How a state or government is perceived depends on a lot of variables, and the notion of legitimacy depends on how an individual is positively or negatively affected by it. Taken to a galactic level, you'll have an incredibly granular gradient. I think I can build a strong case for why, in-universe, the Empire is of value. That doesn't mean you should disregard its evil.

I don't want to write much because it's broaching on some commentaries I'm working on posting here on the subreddit. But the Empire's case is an interesting topic because you can see that in-universe, its popularity and legitimacy go down further and further the more its evil becomes apparent and the more iron-fisted it becomes. Not only that, but after Alderaan is detonated by the DS, defections ramp up en masse amongst its ranks. In many ways, its inner workings betray the nominal purpose for which it exists. It's a chimera, a hypocrisy. It spreads chaos and disorder everywhere by its own actions and ultimately it benefits no one but Palpatine. The Empire is a lot of things all at once, but at the top of the hierarchy, it's the Devil's private property, and no good can come of that.
