Your saying you do not dispute being human and connecting to the story while saying it is pointless to apply real humanity (psychology, how people work and talk and think and act) to the story.
Look, the point I'm making is this - your way of describing the story fundamentally lessens it in my eyes. If Luke's surrogate parents are talking about their concern for their young boy who is trying to join a war when he has no idea what he's actually in for and relating that to how his father did the same and now he's gone, that's a believable human moment. That's good writing. If they're talking how he might just...arbitrarily become a murder fascist because his dad was one, then what are we even talking about? What am I supposed to take from that other than that genetics work differently in this place, then Luke is effectively less human as he's going to be making decisions that have no grounding in believable human behavior - he just might be a murder fascist just because it's in his genes, which is the same thing as saying "just because he is" in terms of narrative.
And this is all demonstrated how bad this writing is when it's made explicit and brought to the forefront: Palpatine telling Rey to kill him so she can become the new Empress and he can act through her, and she has no fucking reason to want this, but she have to pantomime how this is somehow an actual dilemma for her because she has the palpatine evil genes. Again, what is anyone supposed to take away from this? Nothing because this isn't anything that anyone actually deals with. There's no meaning to it. It has all the satisfaction of seeing rocks fall because the gravity pulls the rocks down to the center of the planet due to it's density. Okay, so what? It's just gravity. It's just genetics. It's just things happening without meaning. Meaning is what makes stories great, and meaning only happens through humanity.
So if you still don't get what I'm talking about after that, I genuinely don't know how to explain it to you. All I can say is what I said earlier - that if I saw things your way, I probably wouldn't be a star wars fan at all.
