Shiva. Reminded me of a plot from Tom Clancy’s “Rainbow six”.

“Clark and his colleagues become suspicious about the recent, sudden increase in terrorist attacks. Unbeknownst to them, the first two attacks are part of a master plan to wipe out the majority of the human race, called "the Project". Dr. John Brightling, a staunch environmentalist who heads a biotechnology firm called the Horizon Corporation, had orchestrated the attacks through ex-KGB officer Dimitri Popov in order to raise awareness of terrorism, which then helps former FBI agent and co-conspirator Bill Henriksen's security firm land a contract during the Olympic Games in Sydney, Australia. From within the Olympic security apparatus, Henriksen plans to launch a sophisticated bioweapon attack using nanocapsules containing the Shiva virus, a mutated form of the Ebola virus that had been previously used by Iran during its biological attack on the U.S. (depicted in Executive Orders). After the epidemic starts at the conclusion of the games, Brightling's company would then distribute a vaccine that actually contains the virus itself, effectively killing the rest of the world's population that are not infected with Shiva. The "chosen few", having been provided with the real vaccine, would then inherit the emptied world, convinced of their justification for mass murder as "saving them”

“Rainbow Six explores the issue of radical environmentalism. According to Marc Cerasini's essay on the novel, the philosophy of the antagonists are considered as an extreme form of naturalism, based on Jean-Jacques Rousseau's view that society's functions corrupt mankind and that "a natural or primitive state is actually morally superior to civilization". The novel shares elements found in James Bond movies: a biological weapon being used to end the human race, mad scientists plotting world domination, and high-tech secret bases hidden from civilization. However, Clancy makes the plot realistic by basing the motivations of the eco-terrorists on real-life radical environmentalists.[2]“
