Nihilitarianism

I'm staying at a warehouse community right now, and it's called Omega. I came down with stomach flu here: they call it the Omega virus. It struck me as a good name for an apocalyptic pandemic in a cheesy scifi. Like a plague sent by some alien superorganism. But it doesn't just kill anyone: it just culls anyone that doesn't conform to their standards, so that they can assimilate the DNA of those who do. Most affected humans die, and only those loyal enough to be suitable as servants survive. When the survivors become isolated from the rest of humanity, the entity releases a manifesto to brainwash them, and they're ordered to kill any human who hasn't been infected. At some point the uninfected find out how to cut off aliens from their hive mind and learn that they used to be a peaceful telepathic species, and became a superorganism when the elite used the virus against the system that came before it. When finding this out, the uninfected use their virus against them, since they're not loyal either. It can be seen as an analogy of the communist revolutions where the leaders didn't conform to their own standards of selflessness.
