If we apply SW lore to modern politics (Biden was like 30 something when the original Star Wars came out... consider that... almost 50 years ago) Vader is basically Biden and the Emperor is, I suppose?, Trump.

You can get the guy shooting lightning out of his non-functioning cock and openly just saying "yeah, we gotta kill all the other species or otherwise enslave them so fucking what?"

or you get the "lesser evil" going around, chopping up younglings, fire bombing and genociding entire planets for resisting the empire... but maybe he feels a little bit bad about it.

He's just killing all these disgusting non-empire, non-humans, non-subservient planets/species because they said they don't want to live under the yoke of the empire. "That's anti-imperialism, man! Come on, man! Just sit back, let me swing my giant red laser-dildo around a few planets, maybe daddy can blow a few up, and hey, I bet those dog-creatures on Kashyyyk realize their knees can bend after all. It's all gravy from there! Just stop being so fucking liberal, ok!? Millions of empire-haters gotta die. We all must live with this fact. Please just shut the fuck up about it already because you're kinda starting to sound like you also hate the empire and my dildo-trigger finger is getting very itchy. All these questions are making Vaden very angry!"
