Well, to be fair, knowing that killing Yu-Yevon would break the cycle isn't the same thing as knowing how to kill Yu-Yevon, since you have to get through Sin first. So Operation Mi'hen would still have probably failed.

On the other hand, if Yevon was sincere and open about getting rid of Sin, there would be a thousand Crusaders waiting each time the Final Aeon was summoned to finish off the jellyfish before the new Sin is formed.
