Well yeah, there is that argument. But whose to say that he will be able to control Sin once Bevelle was destroyed and prevent it from destorying Zanarkand as well. This way, he can preserve Zanarkand with even more control than before and can still destroy bevelle should Sin happen to be passing. By destroying Zanarkand as Sin, his given the survivors a reason to become the Fayth, to preserve in a dream what was lost in reality
