Something Luke would do would be to collapse/complain/whine.
Episode IV: "It just isn't fair, I'm never gonna get off this rock." "But it's a whole 'nother year." "With the blast shield down, I can't see the remote, how am I supposed to fight?"
Episode V: "I can't do it, it's too big." "Master moving rocks is one thing, this is entirely different." "You aren't/(ask?) the impossible.
Episode VI: "Then my father is truly dead." (Kinda silly to put all your eggs in a basket then haphazardly decide that he's gone. Unless it was reverse psychology, colloquially known as a "Mind Game." Not a Jedi Mind trick but toxic manipulation through the use of the false dichotomy fallacy. "NEVER!" (Remember that time that Luke responded out of _rage_ when Vader threatened to turn Leia? that was awesome.)
"Fear leads to anger, anger (see rage) leads to hate, hate leads to the dark side."
All of those emotions can be internalized, you don't have to feel them in regard to others. Yoda had internalized fear by simply fearing the dark side. He was blinded by his fear. Luke had followed Yoda/Ben's footsteps.
Rian Johnson's writing for Luke was on point and consistent with the character AND representative of how a student can repeat the mistakes of the master. TLJ was about Rey and Luke breaking the cycle.
