"You have no idea how this ring works, do you? Why the Forerunners built it? Halo doesn't kill Flood, it kills their [i]food[/i]. Humans, Covenant, whatever! We are all equally edible. The only way to stop the Flood is to starve them to death, and that's exactly what Halo is designed to do; wipe the galaxy clean of all sentient life! You don't believe me? Ask him!" The greatest video game plot twist ever...Of all time.
