This is my recollection from Planescape: Torment: Colons:
As I stood face to face with my own mortality (literally), I came to the realization that I had accomplished all that I could hope for, I was moments away from achieving closure after all this time. And yet, it I could not have felt worse at that time. All my friends, those who had traveled with me in a completely senseless quest for me to finally die were killed one by one when we entered this plane, and there was nothing I could have done about it. It would all be O.K. if I could just convince my mortality to just give up and join me once more. But I wasn't strong enough. I could not convince it to forsake the freedom it had had long to enjoy, to be one with me so that I may finally *know* death.
Before the final battle, it did offer me one thing: I could revive one of my companions so that they may live their lives where instead they had followed me to their dooms. Should it be Morte, the talking skull whose guilty conscience forced him to remain faithful to me for what may have been centuries for all I know? Should it be Dakkon, the warrior who I tricked into a life-debt many lives ago whence I was a much crueler version of myself? Or Fall-From-Grace, the succubus who left tortured servitude on a hellish plane and chose to follow me partly out of pity? Well at least I don't have to worry about Vailhor, that guy was *nuts*.
Well there was one thing that clinched it for me. All the souls noted above could at least have given me the comfort of knowing that their deaths brought some sort of closure to their tortured existences. But I couldn't say the same about my 5th party member, Annah. I'm actually not sure what exactly set her apart, maybe it's just because she was the one I fell for, but if I had to save just one member of my group, it had to be her. So I walked over and brought her body back to life, and after a heart-felt farewell, she was portaled off, leaving me to confront the spirit of my own mortality on my own.
Needless to say, this enchanting game pitted my stomach more than once.
