ugh i get ENDLESS feels about Luke's micdrop line:
I'll never turn to the dark side. You failed, Your Highness. I am a Jedi. Like my Father before me.
because Luke isn't saying he is a Jedi like the Order were Jedi. A Jedi who shuns emotional knots and strives for emotional neutrality. He is a Jedi like his Father, like Anakin Skywalker.
The type of Jedi Anakin was.
Even in ANH he doesnt say he wants to learn from the Order. He wants to learn how Anakin did it.
And he does. In time, he allows married and older Force-sensitives to join his Order, he embraces attachments (and even marries himself and has children in the EU).
And at that pivotal moment in TESB: Luke is clearing the guilt and torment of his father - he is holding up Anakin's dream: the dream of being emotionally invested, attached, loving, fighting for that love, and it making him strong and noble. He is holding up THAT dream, the one Palpatine used (and the Jedi Order to a degree in their fear) to convince Anakin he was weak, a failure. Luke is holding up that dream and saying No. No it makes me strong.
And you can't use it to turn me to the Dark. As Luke watches the fleet under attack and Sidious mocks him, tries to use his attachment to his rebel friends to weaken him, Luke uses his love for them to keep him strong, to help him resist. To not give in.
When Vader watches Luke do this-- this alter-ego, this dark Phantom must melt in the acid that is Anakin's psychological resurrection.
Luke doesn't want to be a Jedi like the Order. The Order failed, according to Yoda. Was blinded.
Luke wants to be a Jedi like Anakin was. A different kind of Jedi. A Skywalker. He saves Anakin's soul by showing him, Sidious, and the galaxy that great goodness can come from Anakin's way.
When Anakin is dying and Luke weeps, "But I have to save you," this is what Anakin means when he says:
