*puts tinfoil hat on*
Emperor Palpatine is the only good guy in Star Wars.

The reason he wanted to create the Empire is that he know aliens from outside the galaxy were preparing to invade. And these aliens didn't give jack shit about the universal law of the galaxy (the Force itself. They were literally immune to it). So to protect everyone from these illegal aliens that planned to break the law, he had to unify the galaxy through a Grand Empire.

But Disney discovered that the true sequel to the Star Wars story was such an effective propaganda piece against illegal immigrants, and they had to stop it, because it conflicted with their own plans of removing borders in the US.

They also had to proclaim The Expanded Universe non-canon, because that's where the truth of Palpatine's Empire currently resides in.

Well that was fun. Maybe I'll do that again.
