is that, at least to my admittedly extremely limited SW lore knowledge, there's no reason why the prophecy of Anakin "bringing balance to the Force" has to be taken as a prophecy of *all* of his actions. Although of course people are naturally inclined to read it differently, prophecies have a way of meaning something else than people are inclined to think: at some point in the future, Anakin will bring balance to the Force. That's all the prophecy says. Anakin's actions prior to that are entirely ignored. So in that view, Yoda and the others were right to consider the "bringing balance to the Force" a good thing - but they failed to realize that prior to that, Anakin would be a main factor in unbalancing it.
