I just hope that if Rey has already built up the new jedi order again or if she finds some of Luke’s old students, that they show that they aren’t the same as the Jedi from before Order 66. My biggest question as to why Luke was bashing the Jedi was because he should’ve already fixed the problem. The Jedi clearly had a problem, and Luke clearly defied Yoda and Obi-Wan’s wishes by not conforming to their beliefs in ROTJ. Why would he bring back the jedi order, not change the teachings, then blame the Jedi for their ways after they’re all killed off again. That seems like a “no duh” situation.
I think that’s a big factor for why people think Ben Solo will be redeemed; so far we’re told that he was in the exact same situation as Anakin was. If Ben still turned despite Luke changing the jedi ways, then I feel there would be a significant drop in redemption believers. Not saying it’s a bad thing to think that, but that’s just how I see it.
