Why do we think that Luke was going to kill Kylo? Luke has the would you kill Hitler as a child decision and he couldn’t do it. He considers it but can’t.

To me this is well within his character. His father was responsible for the murder of millions after being trained when he was too old. In the same way Ben and Leia sent Ben after Snoke had begun to influence him. So Luke is asked would you kill Hitler, he decides no he can’t do it and then REN wakes up.

Luke’s weakness is fear of the darkside. A fear of Lord Vader and after all of these years still has not conquered it. Luke being a flawed failed Jedi is a reasonable outcome for a farm kid forced into war and dealing with the fact his father was a genocidal monster who was redeemed. The conflict between seeing the light and being afraid of the Dark both within himself and others informs the action we he looks into Rens mind and sees his future.

The conclusion of skywalker was also apparently based on George Lucas notes and not a Rian Johnson original take. It’s a great end to his arc as a tragic hero
