So, in your interpretation of the OT, regardless of the PT, Luke could have killed his father and still walked away the good guy?

What? No! Did you read the links I posted? You seem to have grossly misunderstood what I was trying to say.

Maybe I wasn't clear.

What I'm saying is that Luke could have killed Vader and the Emperor and walked away thinking he was still the good guy. But that would have put him on the path that Yoda said would FOREVER dominate him.

Edit: Also,- whaddaya mean "short"? Working himself up to the level of rage so that he KILLS HIS OWN FATHER! How is that short?

I mean one action taken in a 10 minute fit of rage would not immediately overthrow his sense of right and wrong once he calmed down. How many people do you know completely change their personalities in a single day?

I'm saying Luke would have taken his first step down the path of the Dark Side. And that there would have been many more. But he wouldn't have already arrived.
