This makes for fantastic dystopian fiction fodder. Two opposite storylines come to mind. In the first a dark cabal seeks to cull the global herd. They create a scare for some innocuous virus and get people to inject a "vaccine" into their bodies. They then release a second virus that targets people who have been "vaccinated" that kills them. This leaves what they consider an independent and free thinking people and to usher in a new age of man. Actually, this has sorta been done very nicely in the original BBC series "Utopia"; not the crappy US remake.
In the second plot, a dark cabal seeks to cull the global herd of free thinking, independent people. They create a scare for some innocuous virus and get people to inject a vaccine in their bodies. They then release a second virus that targets people who refused the shot and it kills them. This leaves a more docile and pliable populace to them to rule over.
Before anyone gets butt hurt, and thinks I'm talking about them, remember I said "dystopian fiction? None of what I outlined has anything to do with real life...or does it?
That story has already been written. Twice.
H.G. Wells' 'The Time Machine', featuring the Eloi and the Murlocks.
Then again in the movie 'Serenity', starring Humans and Reavers.
That’s exactly what I’m referring to.
And who are the people more afraid of dying and more willing to bootlick just to ‘live’?
