“Gandalf as Ring-Lord would have been far worse than Sauron. He would have remained ‘righteous’, but self-righteous. He would have continued to rule and order things for ‘good’, and the benefit of his subjects according to his wisdom (which was and would have remained great). Thus while Sauron multiplied [illegible word] evil, he left good clearly distinguishable from it. Gandalf would have made good detestable and seem evil.” – J. R. R. Tolkien
