AI Narrative : Virtual Being interaction as a narrative device.

I had a query about whether can help me to create a character that will, on interaction, decide the fate of a player. So, for example, on meeting the mystic character, depending on whether the player pleases or aggravates her, she will decide if they go to heaven or go to hell (return to the start of the world again). 
Guy Gadney kindly advised that it is possible to create a single ‘scene’ that directs to two sub-plots. A condition could be put on each subplot. So for example the heaven route would lead to the experience end while the other returns the player to the start (in a non-linear way). 
I’m not entirely sure how this will work in practice but I’m thinking that it may be possible that interaction with mystic can be positive or negative depending on her AI responses (input from her back story). So for example, if she doesn’t like swearing then if the player swears at her she could send you on the track to hell.. back to the start. Whereas if you were to flatter her, she might warm to you and send you on to heaven (unless you are being insincere of course!).
