Well, I think the outside perspective is that Kreia is wrong about her interpretation of the Force - she sees it as some independent, meddling entity that plays the inhabitants of the universe like puppets and fools; that the universe would be better off without it, with living beings exercising free will. I guess the Mandos might go along with that, but that's a little too easy; maybe the better fit would be the Corellians, with their own peculiar mythology and, within the context of the movies (if we take Han as a reasonable example of a Corellian) deep skeptics. Of course, the punch line with the Vong is that they weren't really severed from the Force, and in the end were just within the purview of prophecy. Back to Vegere, I think she holds a role similar to how Lumiya was in LOTF (at least in the first novel) - trying to guide Jacen onto her own path. If we add in her appearance in Legacy... hmmm. Well, that's probably leaving the bounds of the discussion. Suffice to say, at the very least she represented heretical notions regarding the Force, and the idea that Jacen became interested in variants other than the standard Jedi actually fits, IMO.
