Oh, there is NO question that we COULD get into that. Ab-so-freaking-lutely.
But will Disney do that? No. It would "tear down" everything George built.
Bottom line, good guys have to win, always. We all know that about movies, but it's why Empire Strikes Back was so great, the good guys got their ***** kicked.
Later on in the books (not mentioned in your link) the new admiral chick has a convo with Luke who has worked hard to rebuild the Jedi. She speaks flat out about Episode IV, when he first met Ben. She says two Jedi walk into a bar, a fight breaks out, and a Jedi cuts a mans arm off. The Jedi leaves, however he wants, when he wants, without being questioned. No police interview, no military involvement, he cuts an arm off, and walks, free. He's a Jedi, can't touch him. Luke sees it as simple, yes, Ben was a good man, he was a great Jedi. She counters with, so was Anakin Skywalker. How do WE know when a Jedi blurs the line between right, wrong, fair or not?
That my friend, is where the galaxy CAN go. Will it ever? I doubt it. I doubt we will ever get to see the "Jedi way" questioned, we'll just see good guy, bad guy. Good v Evil. But anyone that is a true fan of the series knows that you COULD chop it up real good in this whole Sith v Jedi thing and make BRILLIANT films about it.
Now, I paraphrased alot of that convo, there was much more to it, but put it this way, I couldn't stop reading that ****. Luke's whole ideal was ****** up. And as we all know, Luke is a "good" guy.
Luke also turned to the Dark Side once.
I'll stop there.
