My thoughts: I am thinking, based on Luke’s words, that it might be heading towards my own interpretation of what ‘balance to the Force’ means – that we have to accept light AND dark together, and not as a schism. More of a Jungian POV. An integration and a stance of acceptance.
Although it could be taken as wanting to wipe out all the information/knowledge altogether, forever. I don’t think they will go there – it’s a tad depressing, very conservative, and doesn’t seem to fit into the Journey of the Hero. “Refusal of the Call” only happens early on in Campbell, and is subsequently overcome by the hero taking up the mantle (often after their families and/or mentor dies…and both happen with Luke).
It looks like Luke has a small library of the earliest Force knowledge in that First Jedi temple. Maybe we [the viewers] will start to learn a few things. I think we’ve waited long enough for it…since 1987?
For fans of Dune (the book)…doesn’t Peo Dameron remind you of Duncan Idaho? At least that is how I picture him.
