[@Roseletta]That sort of a 'Yes and No' kind of thing. Nidhogg is the product of a violent possession, and as such, he still feels fragments of his old personality because it's still in there, buried deep within his current persona. And buried even deeper than that would be the original Nidhogg, the ball of primal hunger, instinct, and base destructive, self-serving impulses that is completely and utterly inhuman. So he kind of has Split personality disorder, but not really. That's my take on it, anyway.
