“Rael Averross: "Let's say I believe that some day there's going to be perfect balance in the force, thanks to some kind of chosen one. Did you ever really think about what that would mean Qui-Gon? It would mean the darkness would be just as strong as the light. So it doesn't matter what we do because in the end, hey, it's a tie. It doesn't matter which side we choose."
Qui-Gon straightened and deactivated his blade. Rael took a step back, lowering his lightsaber but keeping it on. "It matters." Quin Gon said quietly. "It matters which side we choose. Even if there will never be more light than darkness. Even if there can be no more joy in the galaxy than there is pain. For every action we undertake, for every word we speak, for very life we touch, it matters. I don't turn toward the light because it means some day I'll win some sort of cosmic game. I turn toward it because it is the light.
.....
Averross: "You've made mistakes Qui-gon. You've touched darkness."
Qui-Gon: "Yes i have. No doubt I will again. This isn't a choice we make once and walk away from. It's the work of a lifetime.”
