SPECULATION “Once you start down the dark path, forever will it dominate your destiny, consume you it will.”

Well it would ruin the Saga. I mean the point was that Luke resisted and won. Not resisted and failed half way before the credits rolled.

Second, Yoda's words everyone wants to understand one way. That if you start down the path to the Dark side you can't come back. First if that was true how was Vader redeemed clearly he went down the path but was able to come back. That seems too simplistic for Yoda at least to me. I think Yoda's warning is more about the consequences that may be faced how it would haunt you not that you could never turn back. Meaning if Luke acts in hate and so forth he may come back to the light but the results of his actions would still haunt his destiny.

 

Yoda's were wise but I don't think Luke's experience with the darkside would end in TROTJ, that gnawing feeling will never go away as long as he lives.

 

In an earlier draft of the script of ROTJ George Lucas planned it as the following:

Luke resists the emperor and safes his father. Darth Vader kills the emperor, takes of his helmet and dies. All this is like it's in the final movie. But from this point it becomes different. After Vader dies, Luke holds his helmet in his hands. He then puts the helmet on and gets overwhelmed by the dark side. After this he decides to follow in his fathers footsteps and become the new Darth Vader. He becomes head of the empire and ruler of the galaxy.

The ending was changed in later scripts, because it was considered too dark.

 

I feel like after everything Luke went through in that last movie would just make him stronger in keeping his commitment to the lightside of the force.

 

They probably changed that ending because it was too dark....and utterly ridiculous.

I know Lucas likes to end things with a twist but that would have been such an absurd ending, it would have made the droid factory scene in AOTC look like pure cinematic gold.

Sometimes I forget though that even by 1982, Lucas was already losing the vision for the series.

 

It was something about Darth Vader's helmet. The helmet is possessed by the dark side or make you possessed by it.

Also, originally it was planned that we would have Wookies in ROTJ instead of Ewoks.

 

People keep pushing the "Luke is nuts." angle WITHOUT any real, documented proof or data to support it.
Think about it!
Would Disney & ILM turn one of the biggest Star Wars characters & one of the most interigal figures to the entire story line or plot into a drooling looney-tunes or crazy hermit?
It's already been noted that JJ & Kasdan made major revisions to the first TFA screenplay by David Arnst.
I think Arnst's SP may have been to bold or dark(major characters turn evil, extreme violence, gore, etc).
Like it or not, Star Wars is now a Walt Disney property.
I highly doubt Luke will be bat-#%+= crazy or a bad guy. Luke might have a huge battle scene, lose, then become a recluse or feel depressed but he won't be like Obi-Wan or Yoda.

 

Sounds more like that was written by Kasden and not Lucas

 

It should be clear too that GL has pretty much severed all formal ties to the new films(TFA, EP8/9).
He told both domestic & intl media sources he didn't view the teaser TFA clip,
I DO think Lucas(and maybe Kathleen Kennedy) pushed for Kasdan to get a more involved "above the line" stuff with TFA. This is why I think TFA will be more like the blockbuster Raiders of the Lost Ark(1981) & not The Empire Strikes Back(1980) in terms of tone & storyline.
