Balance to the force?
I was thinking, what does it really mean to bring balance to the force? Anakin was supposed to bring balance to the force, not to join the sith and leave it in darkness. On a sith perspective, to bring balance to force would be as it is, the darkside of the force would be ahead. The prophecy suggests that one will bring balance to the force, which is implied that it is jedi prophecy. So in order for the force to be in balance, the sith would be destroyed and only the good side of the force would be around.
I would think that in order for the force to be in a balance, there would be an equilibrium of the good and darkside of the force. So, it already is in balance with good and evil in EPIII.
If not an equilibrium, then it is based on the perspective of a sith or a jedi. Both sides believe that the one side of the force should overcome, then will be in balance.
