I really like that. That way he’s left them to become a Jedi, as per their dogma, but also swung too far from the lesson in ESB that being too compassionate can be a trap, especially when you’re not ready. But here, when his training is complete, he finds a middle path- setting him up as part of the new Jedi paradigm.
With this, would you have him sense that the others have failed? I suppose it could work with or without- his arrival at Tattooine could just be a suprise without revealing him sensing it to the audience.
