Either Luke has a lesson to learn - that the Jedi are ultimately necessary and not a root cause of suffering/evil - or 😦
Sounds to me like they have a little learning to do from each other - Rey needs Luke for her training, but old Luke needs the youthful Rey to give him back a little hope…
As Max von Tekka (sic) said “Without the Jedi, there can be no balance in the Force…”
