Irrelevant for E. The Oracle does not care about Vaarsuvius living or dieing.
Irrelevant for Vaarsuvius.2. The Oracle does not enjoy death or pain, and prefers not to go through them if he has the option.
And very apparently he did that. Sadly, he did not tell us anything about it but a begun sentence which lets us assume is going to die within the story (or... not; not is also possible).3. The Oracle can see V's fate and death if he wants.
Yes, therefore, it is irrelevant for determining if Belkar will cause Vaarsuvius death.4. The Oracle would not be negatively affected if Belkar caused V's death.
So far, we were not even talking about that. But I like to chime in again in what I usually say in this thread: The axioms you base your predictions on are not good enough for that prediction.These, along with what happened so far, are my "external knowledge" I used for making my statement about whether Belkar will cause V's death.
