Return of the Jedi Luke continues to be the worst Luke
I've said this on other boards - The Last Jedi, I think - but Luke at that part of his life blows. He's robotic, intentionally emotionless - it peeks through at times in ROTJ - and cold. He seemed to believe this is how he has to be in order to be a Jedi.
All those complaints about The Last Jedi, but THAT is Luke. An older Luke, but the guy we saw in in ANH and TESB. That guy had emotions and a personality. That's who he was most of his life. He got full of himself and cold during the ROTJ time period. It was a period in his life, but overall, he was always an emotional and caring guy.
