Luke pointed out that the emperor’s overconfidence was his weakness; so, in my opinion, the emperor would not have made plans for his own demise because it’s something he never foresaw.
I hope the next movie doesn’t involve the evil Galactic Empire. Seeing the Death Star blown up twice by the Alliance taking advantage of an architectural defect was enough for me; and in “reality” I’ve seen it blown up over 40 times, if I count the number of times I’ve seen the movies.
I believe without a doubt that we will be seeing the Empire again. As strange as it may seem. Just like in our world, we took out the head of Alkeida but the entity is still around. So imagining a 30 year time span where the Empire has been secretly rebuilding itself under a new leadership is not too far fetched. In fact, it is a realistic story plot. I am hoping it is a leader that is far more different than Palpatine, more dependent upon his followers, and hopefully also, better plans for super space stations… Ha ha ha
As for Luke’s statement. I believe Palpatine had every possible outcome planned. He always had an apprentice, a right hand. We don’t know how many he had out and about in the universe traveling around spreading the seed of the Sith. Palpatine as a Sith believed in a single Sith, infiltrating the system to take it over from inside, through subversion, as seen in episode I to III.
Later when he was in charge, I believe he would have stiffened his grip by bringing the Sith order back, having an anti Jedi group.
This may not happen in the films, but as a leader as he was it would have made the most sense.
The Emperor was quite overconfident, always being in the same place as his super weapons, which was his weakness in the end.
I love these talks. If you have more thoughts, I would love hearing them. In fact I will post these discussions as a page on this blog, so more people can read them as well, see if we can stir up some more as well between us.
