"As for other points. I think I agree about the 'creation by evil'. But you are more free with the word 'creation' than I am. Treebeard does not say that the Dark Lord 'created' Trolls and Orcs. He says he 'made' them in counterfeit of certain creatures pre-existing. There is, to me, a wide gulf between the two statements, so wide that Treebeard's statement could (in my world) have possibly been true. It is not true actually of the Orcs – who are fundamentally a race of 'rational incarnate' creatures, though horribly corrupted, if no more so than many Men to be met today. Treebeard is a character in my story, not me; and though he has a great memory and some earthy wisdom, he is not one of the Wise, and there is quite a lot he does not know or understand. He does not know what 'wizards' are, or whence they came (though I do, even if exercising my subcreator's right I have thought it best in this Tale to leave the question a 'mystery', not without pointers to the solution).
Suffering and experience (and possibly the Ring itself) gave Frodo more insight; and you will read in Ch. I of Book VI the words to Sam. 'The Shadow that bred them can only mock, it cannot make real new things of its own. I don't think it gave life to the Orcs, it only ruined them and twisted them.' In the legends of the Elder Days it is suggested that the Diabolus subjugated and corrupted some of the earliest Elves, before they had ever heard of the 'gods', let alone of God.
I am not sure about Trolls. I think they are mere 'counterfeits', and hence (though here I am of course only using elements of old barbarous mythmaking that had no 'aware' metaphysic) they return to mere stone images when not in the dark. But there are other sorts of Trolls beside these rather ridiculous, if brutal, Stone-trolls, for which other origins are suggested. Of course (since inevitably my world is highly imperfect even on its own plane nor made wholly coherent – our Real World does not appear to be wholly coherent either; and I am actually not myself convinced that, though in every world on every plane all must ultimately be under the Will of God, even in ours there are not some 'tolerated' sub-creational counterfeits!) when you make Trolls speak you are giving them a power, which in our world (probably) connotes the possession of a 'soul'. But I do not agree (if you admit that fairy-story element) that my trolls show any sign of 'good', strictly and unsentimentally viewed. I do not say William felt pity — a word to me of moral and imaginative worth: it is the Pity of Bilbo and later Frodo that ultimately allows the Quest to be achieved — and I do not think he showed Pity. I might not (if The Hobbit had been more carefully written, and my world so much thought about 20 years ago) have used the expression 'poor little blighter', just as I should not have called the troll William. But I discerned no pity even then, and put in a plain caveat. Pity must restrain one from doing something immediately desirable and seemingly advantageous. There is no more 'pity' here than in a beast of prey yawning, or lazily patting a creature it could eat, but does not want to, since it is not hungry. Or indeed than there is in many of men's actions, whose real roots are in satiety, sloth, or a purely non-moral natural softness, though they may dignify them by 'pity's' name."
