Your premise that “permanent death is the only brain state that can’t be reversed, given sufficient tech and time” is absolutely without basis. A technology that could reverse “a million years of terrible pain” is indistinguishable from magic and therefore assuming it could resurrect people (or at least their minds) is at least as plausible.
The first one is reversible, if some advanced enough tech is applied.
The second one is non-reversible (by definition), regardless of any future technological progress.
If a million years of terrible pain permanently destroy human mind, then it is counted as a permadeath. Thus, if some action results in 1 saved life and 2 such tortures, then we must avoid such action, as the action results in 1 net life loss.
On the other hand, if a million years is not enough to permanently destroy human mind, then the action is better than non-action, as it results in 1 saved life (and 2 damaged minds which can be repaired).
There might be technologies that could repair a heavily damaged mind but can’t repair a mind that is thoroughly erased from this universe.
If you create all possible minds, you will resurrect any given mind. Creating all minds is simple in everetian universe, you just need a random files generator.

I think it’s useful to distinguish between 2 types of death:
common death (i.e. clinical death)
permadeath (also known as information-theoretic death)
The first one is reversible, if some advanced enough tech is applied.
The second one is non-reversible (by definition), regardless of any future technological progress.
