[Legolas]

I think part of the reason for this is that Tolkien was very interested in the idea of the Fall of man. Elves were examples of the unfallen man, while men represented reality.

Indeed, I believe this was not the case.

Letter No. 153:

Immortality and Mortality being the special gifts of God to the Eruhini (in whose conception and creation the Valar had no part at all) it must be assumed that no alteration of their fundamental kind could be effected by the Valar even in one case: the cases of Lúthien (and Túor) and the position of their descendants was a direct act of God. The entering into Men of the Elven-strain is indeed represented as part of a Divine Plan for the ennoblement of the Human Race, from the beginning destined to replace the Elves.

Letter No. 131:

I have not used 'magic' consistently, and indeed the Elven-queen Galadriel is obliged to remonstrate with the Hobbits on their confused use of the word both for the devices and operations of the Enemy, and for those of the Elves. I have not, because there is not a word for the latter (since all human stories have suffered the same confusion). But the Elves are there (in my tales) to demonstrate the difference. Their 'magic' is Art, delivered from many of its human limitations: more effortless, more quick, more complete (product, and vision in unflawed correspondence). And its object is Art not Power, sub-creation not domination and tyrannous re-forming of Creation. The 'Elves' are 'immortal', at least as far as this world goes: and hence are concerned rather with the griefs and burdens of deathlessness in time and change, than with death.

Later:

These are the First-born, the Elves; and the Followers Men. The doom of the Elves is to be immortal, to love the beauty of the world, to bring it to full flower with their gifts of delicacy and perfection, to last while it lasts, never leaving it even when 'slain', but returning – and yet, when the Followers come, to teach them, and make way for them, to 'fade' as the Followers grow and absorb the life from which both proceed. The Doom (or the Gift) of Men is mortality, freedom from the circles of the world. Since the point of view of the whole cycle is the Elvish, mortality is not explained mythically: it is a mystery of God of which no more is known than that 'what God has purposed for Men is hidden': a grief and an envy to the immortal Elves.
As I say, the legendary Silmarillion is peculiar, and differs from all similar things that I know in not being anthropocentric. Its centre of view and interest is not Men but 'Elves'. Men came in inevitably : after all the author is a man, and if he has an audience they will be Men and Men must come in to our tales, as such, and not merely transfigured or partially represented as Elves, Dwarfs, Hobbits, etc. But they remain peripheral – late comers, and however growingly important, not principals.

And:

Men are interwoven. For the most pan these are 'good Men' – families and their chiefs who rejecting the service of Evil, and hearing rumours of the Gods of the West and the High Elves, flee westward and come into contact with the Exiled Elves in the midst of their war. The Men who appear are mainly those of the Three Houses of the Fathers of them, whose chieftains become allies of the Elflords. The contact of Men and Elves already foreshadows the history of the later Ages, and a recurrent theme is the idea that in Men (as they now are) there is a strand of 'blood' and inheritance, derived from the Elves, and that the art and poetry of Men is largely dependent on it, or modified by it.

I suggest reading *all* of Letter No. 131 (in fact, I urge you to) as it goes through all of the cycles of the world and the purpose of the events important in the overall scope of the world as far as the Creator and 'gods' are concerned, and the roles of other beings in each. He specifically addresses 'falls' (a term you used):

In the cosmogony there is a fall: a fall of Angels we should say. Though quite different in form, of course, to that of Christian myth. These tales are 'new', they are not directly derived from other myths and legends, but they must inevitably contain a large measure of ancient wide-spread motives or elements. After all, I believe that legends and myths are largely made of 'truth', and indeed present aspects of it that can only be received in this mode; and long ago certain truths and modes of this kind were discovered and must always reappear. There cannot be any 'story' without a fall – all stories are ultimately about the fall – at least not for human minds as we know them and have them.

So, proceeding, the Elves have a fall, before their 'history' can become storial. (The first fall of Man, for reasons explained, nowhere appears – Men do not come on the stage until all that is long past, and there is only a rumour that for a while they fell under the domination of the Enemy and that some repented.

Letter No. 153:

Elves and Men are represented as biologically akin in this 'history', because Elves are certain aspects of Men and their talents and desires, incarnated in my little world. They have certain freedoms and powers we should like to have, and the beauty and peril and sorrow of the possession of these things is exhibited in them.

Letter No. 154:

Some reviewers have called the whole thing simple-minded, just a plain fight between Good and Evil, with all the good just good, and the bad just bad. Pardonable, perhaps (though at least Boromir has been overlooked) in people in a hurry, and with only a fragment to read, and, of course, without the earlier written but unpublished Elvish histories. But the Elves are not wholly good or in the right. Not so much because they had flirted with Sauron; as because with or without his assistance they were 'embalmers'. They wanted to have their cake and eat it: to live in the mortal historical Middle-earth because they had become fond of it (and perhaps because they there had the advantages of a superior caste), and so tried to stop its change and history, stop its growth, keep it as a pleasaunce, even largely a desert, where they could be 'artists' – and they were overburdened with sadness and nostalgic regret. In their way the Men of Gondor were similar: a withering people whose only 'hallows' were their tombs. But in any case this is a tale about a war, and if war is allowed (at least as a topic and a setting) it is not much good complaining that all the people on one side are against those on the other.

(highlights are mine)

Tolkien shares many, many more thoughts on this throughout the letters - I only went through about half.

When quoting Letter No. 131 in another thread, Rimbaud made a good observation that agrees with Tolkien's comments on elves - they did fall:

his [Melkor's] was a sub-creative Fall, and hence the Elves (the representatives of sub-creation par excellence) were peculiarly his enemies and the special objects of his desire and hate - and open to his deceits. Their Fall is into possessiveness and (to a lesser degree) into perverson of their art to power.
