[LotR]Would Melkor and Sauron be forgiven/redeemed after the end of the world, as their actions are fated to be?

If I understand the world of LotR correctly, their actions were mostly fated to be, and they really had little choice. If that’s true, when the end of the world happens, and after the final battle occurs, would they be forgiven by Eru, or are they damned for eternity?
And as a side question, what happened to the souls of the Ring Wraiths when the Ring was destroyed? Would they follow their master into exile, or would they have gone on to the unknown fate that all humans get after dying? I’m curious, because they were misled and then enslaved by their rings.

They weren't "fated" to do anything. When Iluvatar and the Ainur sang creation into existence was a pivotal moment in their lives. This was when Morgoth and his allies sealed their own tombs by trying to sing their own song and change the original. They chose to do this, and this sealed their fate.

Your fate is never set in stone. You can do things that make it pretty much impossible to change the course you set, like what Morgoth, Sauron, and Saruman did.
