That would go against everything they have been building the Titans up for and would be the day I quit playing WoW(or at least quit reading quests and other lore). The Titans are the games biggest antagonists and it amazes me that the majority of the playerbase, even those at least moderately interested in lore, can't grasp that.
Edit: They're also the game's best antagonists. They're not corrupt. They're not evil. They don't desire power. They just don't care.
