Ok, first of all, talking Star Wars, you guys are wrong. We get this a lot. Balance is not equilibrium between Light and Dark. That is a very basic, and totally incorrect, way of looking at it. Wiping out the Jedi did not bring any balance. George Lucas has explained how this works.
The Light Side BRING BALANCE. It is the balancing power in the Galaxy. The Dark Side DESTROYS BALANCE. It is the thing that removes Balance from the Galaxy. Balance is living in a Galaxy where things live in hamrony. As GL also explains, the Light Side is symbiotic- things live in balance with each other. The Dark Side is, by contrast, parasitic- things destroy each other. Only the Light Side can bring this symbiotic universe. Note that The Phantom Menance is full of such symbiotic references as GL hammers the point home.
It is the Sith that unbalance the Galaxy. The way to re-balance it is simply to destroy the Sith.
The Jedi keep things balanced, The Sith destroy it. When Anakin destroyed the Jedi he was abandoning his destiny- but Luke managed to get him back ontrack again. After the films, the Jedi Order will be re-founded, with no more Sith, in a now balanced Galaxy.
You must totally purge the idea of Sith and Jedi having to have equal numbers, or trying to use both sides of the Force, as balance. That is nonsense. I am afraid what JediHDM says is utterly wrong. The Chosen One was not meant to be evil- he was meant to destroy the Sith, that is all. Also, Luke is very clearly a true Jedi after ROTJ- that is the point of the film! Yoda says it very precisely- Luke will be a Jedi, a true Jedi, once he has faced Vader again. You cannot just ignore that.
George Lucas says, after explaining that the Prophecy states that things will become unbalanced, but then can be re-balanced in future:
"The Phantom Menace refers to the force of the dark side of the Universe. Anakin will be taken over by dark forces which in turn destroy the balance of the Galaxy, but the individual who kills Emperor is Darth Vader - also Anakin... the tale meanders and both the prediction, and Qui-Gon are correct."
It is the Dark Forces that do the unbalancing. If Anakin had stayed true to his path, he could have destroyed the Sith and brought balance without the Jedi order being oblitterated, and all would have been much better (though the story would have been much more dull).
So in this case, there is a huge DIS-parallel between Star Wars and Matrix. Star Wars morality is very simple- the Dark Side is evil and utterly without virtue and it MUST be destroyed. There can be no other view on it that is correct.
Matrix mixes it up somewhat, of course.
