[Child of the 7th Age]

Since we don't know what happens in the circles beyond the world, we really have no way of judging whether Tuor or Frodo actually got the better end of the deal. We at least have some images and discussion of the West, so we have some sense how the immortals there were doing. But the circles beyond the world are a big question mark, and there is sadly no way to know.

If we postulate that the circles beyond the world correspond in some meaningful way with Tolkien's own views on the universe as a Catholic, then perhaps we can assume that
an individual like Frodo would come out just fine, but in some undefinable way we can scarcely imagine.
