Gravemind is a purely hostile opponent. He is the embodiment of the Flood, the controling intellegence. Do you think something that commands the takeover of innocent, unsuspecting races could be good or even neutral? The reason he "helped" the halting of the Halo's fire was to prolong the Flood infection. If the rings were activated, no more "food" for the Flood would be present and the Flood's progression would halt.
He only came off as helpful to the MC and the Arbiter becase the outcome favored him and his minions.
