My opinion,I do no think Luke was strong enough to face The Emperor alone,so win in a battle he would not.

Hell if Vader was not conflicted with those emotions I really don't think Luke was strong enough to defeat him either,in my mind,I picture Darth Vader as being one very powerful hell bringer.

I half agree. :-) In my opinion too, Luke was not strong enough to confront the emperor. I thought this before the prequels, and after Palpatine gave both Yoda and Mace Windu runs for their money, I became sure that Luke could not have successfully confronted the emperor.

Vader has always seemed the more powerful Jedi to me too, but that doesn't preclude the idea of Luke beating him. In my opinion, Kenobi would have been no match for Anakin in ROTS if his rage and overconfidence had not led to him making that final fatal leap. While Vader was more experienced in ROTJ, similar factors might still have operated and allowed Luke to prevail.
