Sure doesn't sound extra-galactic. Sounds like the Forerunner were in some way responsible for his existence. Like there was a lesson to be learned from the past. But no such revelations of divine retribution were to be had. What we got had far less resonance.

There were so many memorable lines throughout the series that hinted at one thing, but turned out to be dead-ends or hanging threads. That's just another in a long line of examples.

As far as I know, the Flood is characterized by an undifferentiated "supercell" that can be arranged to perform various biological tasks. So, the infection forms are just blobs of Flood supercells and the hosts have their DNA rewritten to convert them into larger blobs of Flood supercells. "No human life signs detected; he's one of them."

A Flood is a Flood is a Flood. Or at least there's no reasonable explanation that they shouldn't be. All or nothing is a much more elegant solution than this crappy, convoluted mess of an explanation that has been retconned into oblivion.

Either the Halo activation spares Flood supercells or it destroys them. There's no logical way it can spare infection forms, while taking out the larger ones.

By the way, does anyone know what the rings actually do to their victims? Does the signal vaporize them or does it just drop them dead, in which case the Flood would have no problem ravaging their corpses.
