Food for thought for tonight:

What if the Jedi were destined to fall? The same for the Emperor? Why did Luke survive?

"Balance to the Force" - maybe Lucas had something here.

I'm noticing this idea creeping into my thoughts for the NPT. Yoda always said, "Once you start down the dark path, forever will it dominate your destiny." BUT that's not really true. Luke had several dark moments in ROTJ to be at least considered STARTING down that path. He nearly killed his own father in anger, but was able to pull himself back. Not exactly FOREVER DOMINATING.

So what I'm saying is... What if the Jedi were wrong? What if the Emperor was wrong too? All people have good and bad sides. The really messed up ones are the ones who completely surpress or ignore the EXISTENCE of either side. If you go through life NEVER getting angry, you will probably just explode one day (its in there whether you acknowledge it or not). If you go through life ALWAYS angry, you will probably end up creating MORE reasons to be angry and self-destruct. This idea was even coming out in my outlines. Yoda had basically banished himself to Dagobah to hold back the darkness.

Maybe Luke is what the Force needed. Someone who could recognize the darkness within himself, not deny it and still make the right decisions. He would be whole and stronger for it. MAYBE that even explains the lightsabers. Jedi had blue and Vader had red. Both are primary colors and can indicate a singular focus. Luke's lightsaber was green, a mixed color, a blended focus. Maybe if Luke had done as Yoda said he would have been just as doomed as if he had become the Emperor's new servant.
