I always thought Owen had good common sense. Luke should have listened to him.
Might have had a profitable moisture farm and could have retired to a proper tropical island.
Luke was a crybaby! He didn’t listen to Owen like you mentioned, he whined and questioned Yoda’s teaching, and even though this site has to do with the original trilogy, Luke was a coward in the new film…episode 8. Kylo Ren was his student and when he turned evil, Luke turned his back on the the Jedi! I mean…come on, Vader was Obi-Wan’s student and Obi-Wan didn’t turn his back on the Jedi! I liked Luke the least out of all of them.
Yes, he made a mistake but he got back on the correct path. That’s one of the main themes of the movie.
