It's an interesting theory, but it may be too esoteric for a Star Wars film. Not entirely out of the realm of possibility, but if they went that route it would have to be simple enough to follow.
I suspect that Luke realizes that perhaps the Jedi order and the Sith were both wrong in manipulating the Force for their own uses. That one must live in harmony with the Force in order for the conflict to end once and for all.
It looks as though we may be seeing the Journal of the Whills, aka those books in the teaser trailer, which would presumably be the first teachings of the Jedi. The Whills are a part of the film canon now with Rogue One. My guess is that Luke sees too much of a risk in learning from them or using the knowledge from them to teach Rey and he destroys them. This risk wouldn't stem from Luke's fear of being corrupted but that Rey might be tempted if to turn to the Dark Side if he teaches her too much.
Perhaps Kylo only killed Han to earn Snoke's trust and when he says to Vader's helmet that he "wants to finish what he started", what Kylo is referring to is vanquishing the Sith for good. Or perhaps Kylo is trying to bring Vader back from the grave to learn how to destroy the Dark Side once and for all. Something tells me that he isn't what we think he is and that he will die trying to redeem himself, or team up with Rey to kill Snoke and rid the galaxy of the Dark Side.
Just my two cents.
