So your answer would have been the same..?
Yes, it would still be 'no.' Neither
Isildur nor Deagol 'earned' any special dispensation. (See #6 below.)
1. Both only possessed
the ring for a very short time.
2. Both gave in to its 'power for possession' immediately.
3. Neither ever "willingly" gave it up.
4. Neither ever fought to do 'good' for the 'good' of
Middle-earth and others.
5. Neither had a 'natural right' to cross over, both being of
the race of man.
6. The reason 'special dispensation' would be given is not "that" anyone possessed the ring for a time. It's about
who they are (character) and
what they did with and about it (character worked out in action). It doesn't have to do with the ring. It has to do with the person. (
Bilbo,
Sam and
Frodo particularly.)
As to #3 coupled with #6, it could be said that Frodo also never "willingly" gave it up so why did he get to go? He succumbed to its
evil in the end.
Well... his dispensation came from his long battle, endurance, and work on behalf of Middle-earth in spite of his final failure. And his willingness to undertake such an impossible task, almost surely one ending in death, on their behalf to begin with.
Compare it to the dispensation
Galadriel herself was ultimately given to cross over, and why, though she had previously been banned. And she too resisted the lure of the ring and refused it willingly when freely offered - a test greater than we may realize.
That's all I've got on this one... and the reasons for my conclusion.
(Oh all right I confess... I could say more, but I won't.)
