I think that was part of Shadow's point - a 'young-born obyrith' would, in fact, be a million times more strange and unusual than even someone who was twisted into one, because even the lesser obyriths haven't been created for thousands and thousands of years (mentioned in the Sibriex entry).<br/>From the printed obyriths, the idea is more that they're Far-Realmish unintelligible in their motives. Ekolids just want to breed, Sibriexes don't really want to kill at all and prefer to take captives to experiment on. Obox-Ob is solely focused on regaining his title as Prince of Demons despite being an obyrith, Dagon just doesn't give a crap. Demons in general are the sick psychopaths who kill for giggles (Chaotic), and ascending in personal power is just a means for them to get more power and kill more - it's much more of a Devilish thing to kill only towards pursuit of a goal (Lawful).
