How do you square away your interpretation of the Dark Side with Lucas saying that there is no "Light Side" and the Force is just the Force, with the Dark Side being a corruption of it?
In general, I've never accepted interviews in my critique, analysis or writing. A creator can say whatever they want in interviews, it doesn't actually matter.
Lucas' statements on the Dark Side is undermined by a very simple concept: It isn't canon. There isn't a single version of Star Wars that has ever adhered to this idea.
Return of the Jedi showed Luke rocking up wielding Force Choke. The first Force Power we see on screen is fucking mind control. And even when Disney reset the canon to get everything back to basics, Rey straight up pulls out Force Rage during her fight with Kylo. Then you have Mace Windu's special "Dark Side but Not Dark Side" lightsaber form.
Using the Dark Side in limited quantities is something every Force User does. I think the best example of this is Electric Judgment. Plo Koon used Force Lightning, but did so to effectively be a taser to stun a man who had taken a young girl hostage. There's two ways to look at this power.
An example of Legends not understanding the real Force as Lucas intended.
The Jedi using the Dark Side and giving it its own fuckspecial name to make it sound more just because it's apparently different when they do it.
And if you're not keeping up: The second one is WAY better of an explanation. Like, Electric Judgment doesn't exist. You just used Force Lightning. That's not Vapaad, Master Windu, that's Juyo. You're using the Dark Side, fucking own up to it.
And the thing about the Jedi is that their own ideas about the Force aren't free of evil. Sure, the Jedi by and large favor diplomacy, but the thing about diplomacy is that it's very easy to come to a diplomatic solution when you walk in with the deadliest weapon in the universe attached to your belt. You see this in The Phantom Menace, when the Jedi show up to negotiate on the Chancellor's behalf, the Nemoidians are terrified. They're afraid to go into the room with them.
The Jedi's philosphy is fundamentally "Speak softly and carry a big stick. You will go far."
And let's be honest here: How the hell is Lightning more evil than sticking a rod of superheated plasma in someone's body? That's like saying a taser is more evil than stabbing someone with a blowtorch.
Lucas can say whatever he wants in Interviews about the nature of the Force, but none of what actually goes into the work ever adheres to that. And what's worse, all the best Star Wars media is the stuff that throws that shit away at the first opportunity.
Sure Lucas can say the Dark Side is a perversion, unfortunately Nihilism Grandma said that's cringe and then threw a chair at him.
