rcb said:dude he's right. luke's goal was never to take revenge on the sith. all is goal was is to redeem his father. yes the thought went through his mind of just killing the emperor right there since the saber was in his grasp or force grasp i should say, he through his saber at the emperor's feet once he realized wat he was about to become. he never ran at the emperor saying, "you've succeeded your highness. I am a sith! Like my father before me!" strikes emperor down.
That's something we can all agree on. As I posted Ben, Yoda and Palpatine seem to be keen on Luke killing Vader but Luke was his own person and did the right thing which was the main inspiration for Anakin's redemption.
