ill explain this briefly, the ring destroys all beings capable of sustatining infection forms, and makes them brain dead by destroying nerve and brain activity, BUT the infection forms cant sustatian others, so they werent killed, you should also note that the halos where used 3 times before, as when used the forerunner died from it, so they couldnt correct there mistakes. the infection forms just basicly fed off the dead and/or entered a deep sleep, as with most creatures, in time of survival instinct takes over
as for the gravemind, he is a step up from what keyes was turned into on halo 1, he is also the leader of his group of flood, as the flood mutate easly.
