re: Settle this Episode VI debate for me

Quote: What I have heard, from books taking place beyond Episode VI, was that Luke always walked a fine line between Dark and Light. He leaned to the Light side of the force but he was constantly right on the edge.

I remember hearing that there was also something related to this because Luke wore black in Return of the Jedi. Luke was endanger of falling to the darkside when he defeated Vader, but then decided not to kill him.

Of course, now that I think about it, Anakin was also seen wearing black in Revenge of the Sith. I guess it mirrors when Anakin defeated Dooku, except Anakin killed Dooku at the wishes of Palpatine.
