So you’d torch the sacred texts without hesitation?
That’s the whole point of the scene. The books don’t matter, “Time to look past a pile of old books” Yoda says. He reminds Luke that the inert desire for every person to do good and use their powers to save others and to learn from failure is all that truly matters. Not the old dogmatic teachings of the jedi. And that is precisely the first thing I’ll be cutting out of the film is the books at the end on the falcon.
On the surface maybe that’s what the scene suggests, but it was actually just another fakeout. Rey saved the books (and Yoda knew it). Luke was having another one of his episodes where he goes to do something crazy all hyped up on emotion and then at the very last minute, maybe, decides not to.
