I'm not talking about why he is so pessimistic and miserable, but why he constantly considers changing his mind throughout the film in the briefest of moments before reverting back to how he originally felt. Did Rian Johnson have a reason for this? The end result still has him
fulfilling his wish of dying on the island so why tease the audience repeatedly?
The most notable example that struck me is when he
goes to burn down the tree and the ancient Jedi texts. He stops suddenly, changes his mind, and actively tries to get in to save the texts after Yoda brings the lightning down upon the tree.
What was the reason for Luke's indecision throughout the film, has Rian Johnson commented on this?
