Well, one thing that makes no sense for me is that Kellhus, Cnaiur, even Serwa and Kosoter (if the JE is right) evade damnation becoming ciphrangs or hungers of the Outside or whatever the fuck they become. Why Shae and the senior members of the Consult cannot, they have (at least) the same will of power and resilience than the others to Ascend? Maybe they were convinced of their damnation because they were cheated by the visions of the IF.
