If you read the Silmarillion, it’s also clear that the invisible hands of fate and destiny are ever at work in Middle Earth, and things turn out as they should because they should turn out, in essense. So while the Elves mercilessly destroy Orcs on sight, they treated Gollum with a great deal of kindness and almost like a convalescent. Gandalf knew that Bilbo by sparing Gollum’s life saved himself spiritualy from the evil of the ring, and he perceived that Gollum was not actually evil, but a tragic figure corrupted by the ring and worthy of pity. Gandalf long warned, before Bilbo, that it may be the “weak” that shake the towers of the strong, so clearly he had some vague understanding that it would not be by force of arms or new power of Elven kingdoms that Sauron would be defeated. The “great” people of Middle Earth (elves mostly, but Maiar and Valar as well), have always had “foreboding” visions about the future, whereby they can perceive vague premonitions about the future and the course by which they steer things, and an element of this is clearly through divine inspiration, for as soon as one of the great “falls” into evil, they tend to lose this perception. There is fate, there is foreboding, and there is prophesy.
