Back on Ach-To, we see Luke giving his second lesson to Rey. "Now that the Jedi are extinct, they've been romanticized and deified. But if you look at their story far more closely… The legacy of the Jedi is failure." "That's not true!"
"Thousands of years before their own downfall, they either ignored certain problems or abetted some of the Old Republic's shadiest dealings. Sure, instances like those were few. But at the time, they were too big to ignore for those involved. Considering how high a pedestal the galaxy puts them on, it's a wonder to them how Darth Sidious wiped them out. But now I know why, hypocrisy and hubris, and not just my father's…"
"The most hated man in the whole galaxy, but you saw there was good in him." "And after he came back to the light, I became a legend. Like so many Jedi before, including my own father. The galaxy considered him a hero before the truth of what he has done since the Clone Wars became known. For the longest time, the galaxy believed that Anakin Skywalker and Darth Vader were two seperate people."
