I've only read the first post because I think people started getting into too much spoilers. I've only finished the first Act of Halo 3 so far.
The forerunners I assume were not the only sentient life in existance, so moving away probably would only temporarily fix the problem. The flood would fluorish on all other life, and eventually spread to where ever the forerunners moved to.
As for the whole "what's the point in killing the Flood if you end up dead in the process", my thought is the forerunners may have been altruistic in a way, and they were protecting any life beyond the several galaxies, and protecting any future life that would eventually emerge after the flood was killed.
And whenever there is a movie or a game that the alien reasoning just doesn't make sense to me, I don't think that makes the game unrealistic or unbelieveable at all. I just chalk it up to the fact an alien race would have a different way of thinking and viewing things than us. I mean men and women have problems understanding how the opposite gender thinks. And we are both human. I'd imagine an alien race would have a way different thought process than us.
