I think the cruelest but most compelling part of the Nerevarine as a character is that the prophecy is both something you are but also something you DO. It's not fulfilled by you being born. There were a dozen before you that started with the same percentage of Maybe. You become the Nerevarine, truly, when the prophecy is fulfilled by action. And the final action is destroying Dagoth Ur and the heart, thus destroying the tribunal and revealing them false.
BUT. That could be interpreted as like. It's all creeping up on them, like being haunted, like being possessed, until the last minute. And then it's You.
That's your best friend, and you had to kill him. These were your friends, and they killed you. This was your wife, and she helped kill you once and you can tell she will try again. As soon as you succeed, you carry the weight of a past life's failures and memories and grief in a way that's no longer something separate or other, but a facet of yourself the same as any other
