The Doom of Men and the Ringwraiths

[Amarie of the Vanyar]

In my opinion, what happens to the Ringwraiths can be explained by the following text, which describes what would happen to a Mortal Man in Aman if he were given a much longer lifespan.

Considering that the Nine Rings gave the Ringwraiths an unnatural long life, in my opinion it is resonable to assume that the the effects on their body (hröa) and soul (fëa) could be analogous to the ones described in this text [img]smilies/frown.gif[/img]

But let us suppose that the 'blessing of Aman' was also accorded to Men. What then? Their bodies would (...) not whither or age but would endure in vigour and the delight of bodily living. But what of that Man's fëa? Its nature and 'doom' could not be changed (...) Yet it is (as the Eldar to hold) its nature and doom under the will of Eru that it should not endure Arda for long, but should depart and go elsewhither, (...)
Very soon the the fëa and hröa of a Man in Aman would not be united and at peace, but would be opposed, to the great pain of both. (...) But if he remained in Aman what should he come to, ere Arda were at last fulfilled and he found release? (...) if his fëa were strong, it would leave the hröa. Then one of two things would happen: either this would be accomplished only in hate, by violence, and the hröa, in full life would be rent and die in sudden agony; or else the fëa would in loathing and without pity desert the hröa, and it would live on, a witless body, nor even a beast but a monster, a very work of Melkor
