Ahh yes Luke was hiding out protecting and waiting to train who again? That?s right.... NOBODY
The idea that Yoda was "waiting to train" Luke is silly. There's no logic to it.
Yoda dies of old age less than a year after Luke arrived to be trained. So, saying he waited 20 years after exile (nearing death from old age all the while) to train Luke, yet still needed to be talked into it by a ghost because Luke was *too old* is kinda convoluted isn't it? Not exactly a strong foundation to make the case for Yoda having a higher purpose to his exile after failing to prevent Palpatine's takeover.
Kenobi even waited three years after Luke destroyed the Death Star to even mention anything about Yoda and Dagobah. In fact, he only showed up as a ghost when Luke was in danger of dying after the Wampa experience. If anything, that seems more like what forced Kenobi to come up with the Yoda idea: Desperation because Luke was too likely to get himself killed without further training.
I don?t hate Rian Johnson. I like Knives Out, Looper, Brick, The Brothers Bloom, but Johnson, his enablers, and fans of his characterization of Luke keep demonstrating their fundamental misunderstanding of Star Wars.
It?s been made clear that Jedi don?t even begin to train force users once they reach a certain age because it makes them more susceptible to turning to the dark side due to attachments that they have begun to develop.
Luke would approach every student as someone who has the potential to turn to the Dark Side and their training as something that he needs to do to prevent that from happening.
Like X-Men where Professor X tries to get to the mutant before Magneto does.
It?s not about building an army, it?s about making sure that a force user is trained before they go bad.
He would obviously already be aware that a powerful force user who also happens to be Vader?s grandson has the potential to turn to the dark side.
It would not have been a surprise. He would have been working to prevent this from day one.
When he got the vision, of what he already knew was a possibility, his response would have been to simply train him harder, not kill him.
It literally makes no sense, has no internal logic, and is simply lazy and bad writing.
Man, I'm so glad that my "fundamental misunderstanding of Star Wars" can be corrected here by someone who obviously understands it all so much better. What a relief!
If working from Day One to prevent the dark side taking hold meant that no Jedi pupil could be corrupted by the dark side, how did Dooku and Anakin both fall? It seems pretty evident to me (albeit saddled with this fundamental misunderstanding of the material) that some Jedi will fall to the dark side in spite of the wisest masters around them. The idea of "train him harder" implies that the problem was poor training in the first place. If that's the case, Yoda was a poor mentor (Dooku), and so was Kenobi (Anakin). And geez, they trained Luke. So . . .
The idea that either Luke, Yoda, and/or Kenobi failed with their students who went bad is just a myopic cop-out. Rey actually said it best: "You didn't fail Kylo; Kylo failed you." Self accountability is a thing, and it's good to reinforce it rather than blame everyone else for when someone goes bad. A family of multiple siblings can be raised with the same love, attention, and values, yet one of them can grow up to be a destructive criminal. It happens.
And Luke wasn't trying to murder his nephew when Ben woke up. Luke described what he saw in Ben's mind as "beyond what I ever imagined. Snoke had already turned his heart." Past tense. So Ben was already gone in Luke's estimation. Yet the impulse to ignite the lightsaber was still only a fleeting one, and Luke was immediately feeling shame.
I don't think you have to strain too hard to imagine that Luke would've "tried harder" if Ben hadn't woken up and realized the jig was up on his demented dark side ambitions. Luke's visions of destruction proved accurate. And Ben wasn't scared because he thought his crazy uncle wanted to kill him (Luke wasn't swinging the blade), he was scared because it was obvious that he (and Snoke) had been found out.
