I am curious to know more about Sarevok's "fate" (as I'd put it) in the Ascension. The game is nearing it's end for me, I am clearing Watcher's Keep before going for the final showdown at Throne of Bhaal - suddenly, just after defeating this random monster group in Watcher's Keep, Sarevok began talking to me. First it was about how impressed Sarevok is of the PC's power, how I kill everyone who stands in my way and so forth, but then I changed the topic to that of remorse and nessecity of killing. Finally I got to ask if Sarevok feels any remorse for all the deaths he has caused (even if not directly) - those of Tamoko and his brother Yoshimo. Indeed, it for a while it seemed that I got to see Sarevok's hidden humane side, but then he ended the long conversation by saying; "You presume to know my past, and that you can yank me by some emotional chains - while I have none. This conversation is finished."
Anyways, what I'm asking is this - I assume this is part of possibility of changing Sarevok's alignment. If this is not part of Ascension's "Sarevok possible alignment change" then I am confused, since Sarevok has talked with the PC only once before this and the game is nearing it's end.
