Chaos would REALLY not care if all their food disappears. Chaos has a quite odd hatred for the Materium, the ultimate goal of the Chaos Gods is to destroy the Materium and all that has to do with it (In other words, they would kill themselves to kill everything else)

And Nurgle is not a good guy. He is evil, but not in the same manner as the other gods. Nurgle is like Hitler, he does bad because he thinks it will lead to good. Doesn't mean it is any less evil, nor is he any less evil.

I have to say Chaos. Had you compared the Flood to the Nids, I would say the Flood, but Chaos is the ultimate form of emotion and sensation, including terror. There are creatures in the Warp that cannot be explained that would make the flood, the nids, the Death Star (Not that horrifying, I know :p) seem like a Guardsman with a ruined lasgun on a level of scary. One cannot compare anything at all to Chaos, because it is just so random that anything and everything can exist in it in a way no other things can exist.
