The problems that arise when light is out of balance were teased during the Syrcus Tower quest, actually, as what began the downfall of Allag. Might've been an accident, or a case of the lore team not communicating with the event team, since the rest of the CT story went right back to the "light is absolute good" that FF3 tried so hard to subvert.
