Well, Nancy, Melkor was imprisoned once before by the Valar. They thought he had been rehabilitated and were mistaken; he destroyed the Two Trees of Valinor.
He will return in the end for Ragnorok called Dagor Dagorath. You are right, the outcomes cannot be known by us. I assume he will be vanquished totally, but Eru’s creation is incomplete. Something unexpected may yet happen.
Is Melkor explicitly described as unredeemable?
As I recall, Eru’s creation is incomplete, and we cannot know all the outcomes.
