Does no one learn . . . . The sith arn't the people themsevles, the sith is an ideal, a religion, just like the jedi. A religion that bases itself around the power of the force and those who can use and manipulate it. Even if everyone one who follows the ideals of the sith and that call themselves "sith" die off, they can return at anytime as long as the force exists, and the force exists in all life. (according to the movies) As long as there is life, there will be the force, and as long as the force exists, both ideals will be around, they may dissapear for a while, but they will always come back. But yah, as how StarWarrior knows, i dont know. Becuase george lucas has already got his ideas for episodes 7,8 and 9, and theres some crazy stuff, allota stupid stuff (i seriously hope its really not george lucas's work, otherwise we should all run and hide out of fear that someone could become so insanely stupid), but yah, amongst all the things about Darth vader and luke being cloned and some massive light force wave thing the finally cleanses the earth from the sith ideal, the sith dont "Apparently" die out for quite some time after episode 6. But the whole 7,8, and 9 thing is totally stupid, i really prefer to think it ends at 6.
