So in the deathstar 2 thrown room scene, when the emperor was trying to convert Luke to the dark side and said "you want this don't you?" Referring to Luke's lightsaber on the armrest of the emperor's throne and he says "strike me down with all of your hatred and your journey towards the darkside will be complete" shortly thereafter Luke tries to do exactly that but vader ignites his own saber and blocks Luke's strike saving the emperor.
So why, besides that it wasn't the story George Lucas wanted to tell i.e. I'm asking for an in universe explanation... didn't vader let Luke strike down the emperor, fall to darkside, and then the 2 of them would rule the galaxy together as father and son (like he tried to convince Luke to do in empire)? The emperor was expecting vader to block, and the emperor didn't see it coming that vader was going to throw him in the pit so, and scheming to kill your master and take his place is the Sith way (so it's not like vader thinking that would be unusual/ a tip off)...
Thoughts?/opinions?
It sounds like a great jumping off point for an alternate universe campaign to me...
