For instance, I believe it's detailed in 'Shadows of the Empire', Prince Xizor, of the 'Black Sun' crime syndicate, kills Luke's Aunt Berru and Uncle Owen. He's trying to take revenge for the destruction of his home planet and immediate family by the Emperor's and Darth Vader's experimentation with 'weapons of mass destruction'.
Prince Xizor is ultimately trying to win the Emperor's confidence through guile and shadowy conspiracy.
Throughout 'SOTE' Darth Vader is searching for his son Luke in hopes that he can convince him to join him in destroying the Emperor. The Emperor also orders Darth Vader to bring Luke before him alive, because he has his own plans for Luke.
Prince Xizor conspires to kill Luke and frame Vader for the murder of his own son. Xizor then anticipates that the Emperor will destroy Vader for his disobediece and install him in Vader's place where he can then strike the fatal blow of revenge against the Emperor.
Vader and the Emperor don't kill Luke, because they both wish to harness his ability to wield the 'Power of the Force' to, ultimately, be able to rule their own galaxy and potentially the rest of the Universe, if the 'Force' extends beyond their galaxy. With Luke's powers, in combination with their own, they would have no need of 'Death Star', 'Sun Crusher', 'Center Point Station' type weapons. They could destroy whole solar systems with but a thought. For example, crashing moons into planets, planets into other planets, planets into suns, suns into other suns or just by causing suns to go super nova. All with only the 'Force' as your ally, no technology.
You can't dismiss all of the other 'Star Wars' literature. Lucas is not creating his movies in a vacuum. He draws from the wealth of all of the other licensed Author's works that are out there and he, as faithfully as humanly possible, sticks to the overall chronology and storyline.
The galaxy doesn't fall, permanently, into chaos with the fall of the Emperor. The galaxy becomes a better place for all beings. Like, for instance, the Noghri (I hope I spelled that right). The New Republic rises in it's place, not without many more battles, trials and tribulations, surely, but it does restore order.
That is until a new menace to the Galaxy arises that's even more ruthless than the Emperor.
Question: Since the Arabs are complaining, how did they miss the description of the 'Tusken Raiders'? "Sand people that walk like men, but are animals. I killed them all (Anakin), men, women and children."
Did you happen to see the winning "homage film" on the Sci-Fi Channel? They've been repeating that Special for the past several days, so it's likely to turn up again - or you can view it on atomfilms.com. I cannot recall the name of the winning entry, but the "close combat" scene between the central Jedi character and the Tusken raider ends with the "sand person" being decapitated, light-sabre style. Then his head is lobbed into the air and blasted, like Jedi skeet! The beheading thing sure lends more weight to the Tusken Raider = Arab argument.
Or it could just be a bunch of silly fun, totally lacking in meaning.
