I was just rummaging through the back part of the barrow when I came across
this old thread.
My current curisoity is over the nature of Morgoth's power over Hurin's life. If Morgoth had kept Hurin in that state for a much longer period of time, would Hurin eventually have turned into a wraith of some sort? Obviously, the spirit remaining in the body for an indefinite period of time would be unnatural. Would Hurin have eventually expired in spite of Morgoth's curse or would he have eventually wasted away until he became a Gollum-like creature or a wraith or wight of some kind?
