[Star Wars] Someone made a post about why would Palpatine want Luke to kill him (to goad him to the Dark Side). But what if Luke had actually succeeded in just randomly striking the Emperor down right then and there in the throne room?

Vader probably would have made the pitch for he & Luke to rule the galaxy together as father & son, and this time without the Emperor it might have held more weight; they could end the battle within a couple of minutes, and then start sorting out a general truce between the Empire and the Rebellion as a preliminary to trying to re-establish the Republic...the unreformed Vader and Luke will probably clash more than once as they deal with unexpected political and social pressures, emotions running high, difficulty controlling the two sides of the galactic civil war, and some incident may be triggered where one or both of the pre-eminent Force users is forced to order some brutal reprisal or massacre...

...and that's probably about the time the Emperor will make his startling comeback, since he was a serious body-hopper in the old Expanded Universe.
