"Why doesn't somebody just balefire the Dark One back to before where the taint was created?
Read the previous paragraphs about what BF does, and why it is dangerous to use. Now, supposing that 1) the DO has a corporeal body which could BE balefired, and 2) enough BF could be produced to zap the DO back 3500 years (neither of which is at all certain), consider what would happen to the poor Pattern of All Creation if one of the prime movers in its weaving was BFed. The end of the world would probably happen for sure, then.
Remember that the DO is the source of the whole history of the 3rd Age. Everything everybody has done for the past 3500 or so years has been affected in some way by the DO. Why is Joe Al'Schmoe of the 2 Rivers a farmer in a forgotten province of Andor, and not a citizen of one of the most powerful, strongest nations in Randland? It's because Manetheren was destroyed in the Trolloc wars, which were initiated by Ishamael, who was the DO's right-hand-man throughout the 3rd age. "
