The droid getting sliced in half takes place before ROJ. Assumin gthe deoid repairs itself or someone else does, maybe he is pissed at Vader for doing it. So in revenge he saves Palpatine thus leading to the next set of movies
Yeahā¦ ummā¦ doubtful but okay. I donāt see droids seeking revenge, not in their programming.
And droids shouldnt be able to think for themselves, yet they do! Geez imagine that! And in a fictional movie about people possessing powers and faster then light speed ships!
Are they thinking or reacting based on their programming? Remember, C3PO wouldnāt even tell them the Sith Language cause he was āprohibitedāā¦ they had to reset him and extract it from his programming language to allow him to read and recite. In a world full of droids, giving them programming to seek revenge, Star Wars would have already ended in the first movie cause they would have already revolted and killed all biological lifeā¦ 
Maybe thats the theme to the next set of movies. Hell they have Killer Bounty Hunter robots after all.
Thats why they put in superwoman space Leia in episode 8 if she could survive flying through space so can Palapatine.
And a DROID helped her back into the room ā¦ OMG i smell a conspiracy theory coming !!
Teddy Bears beat the largest most well armed military in the universeā¦ You would think Stormtrooper armor could withstand a large pebble being thrown at it with less than alarming force.
THE EMOTIONS THIS MORNING!! This finale was incredible!!
Armor? Empire goes cheap on armorā¦ they recruit minions from all these habitable worlds so they can die in pointless star wars battlesā¦
