I think the terms “light side/dark side” create confusion themselves, if we’re to understand the light side as being THE Force and the dark side as misuse/abuse of the Force. Saying the Force has “sides” implies an intrinsic dual nature.
I’m sure you’re aware of this but this is why the term “light side” is never actually used in the movies, original or prequel.
The “good side” is mentioned, though. Semantics? You be the judge. I still think use of “dark side” is a misnomer if the Force isn’t meant to be analogous to Yin/Yang. Lucas could’ve found a better way to describe the opposing philosophies of the Jedi/Sith.
I agree that he could have. That’s mostly what I’m complaining about, I just think people in the EU made it worse.
When Luke says that I think it’s more in just the moral sense like we would say it in real life, not indicating a whole new “side” to deal with. The delivery is so fast that it almost comes across as a Mark Hamill adlib.
