The Sith rule of two only came about in the 90's, and was supposedly to explain why Sidious did not have more apprentices. The EU explains this by saying the Sith consume each other when there are more of them. As with most things EU, this is a crock of bull IMO. The only reason Vader turned against Palpatine and threw him into the pit was because he had become a Jedi at that point; as long as he was a Sith he remained Sidious's lapdog. From a common sense POV it makes the Sith look completely stupid. Why would you only have 2 of your ancient order, when a tragedy (like a starship blown up by pirates or something like that) can wipe out your entire order and it's teachings. It would have been MUCH better IMO if there had been just as many Sith as Jedi in the PT. Sidious however, would have been a powerhungry and insidious sort, and in the end would have betrayed BOTH the Jedi and the Sith via Order 66, killing them all. He would not train anymore Sith because he would want all power for himself and not share it. He would keep Vader because his status as a Chosen One would please him, because he managed to turn the Jedi's most valuable asset against them, and Vader's constant presence and suffering would make Sidious happy and keep reminding him of his genius. So basically, the PT would show that it was only Palpatine who was a vile and conniving sort who would turn against his own kind and the Jedi in his lust for absolute power, not that every Sith is like that. If you believe the latter, as we have been led to believe, why the heck would any Sith train an apprentice, if he knows he is actually training his potential future violent and painful murderer? And wouldn't it have been awesome on Geonosis to have seen an army of Jedi take on an army of Sith, instead of droids and winged bugs with sonic weapons? It would take around just as much CGI as those scenes already did (unless if you believe those droids and genosians were real ) Thoughts?
