Worshiped as 'space gods' by many races, they may be benevolent by their own lights (unlikely as they often act robotic and rather malevolent, save perhaps to their creations, the Eternals), but they have absolutely no regard for the interests of anyone but themselves. They consider virtually all other beings 'germs' (much like the Monitors of DC multiverse), and destroy entire worlds and species if they think it necessary. Even the Watchers are not safe from their judgment.
