Who is John Brightling from Rainbow Six and what is their importance?

Brightling is the CEO of Horizon Corporation, a U.S. multi-million dollar pharmaceutical concern. His company is involved in research on an Ebola-like virus named Shiva. Shiva has taken the Ebola virus and re-engineered it by grafting colon-cancer RNA into the host organism, thus creating a robust and deadly killer. Brightling and his devoted staff are radical environmentalists who feel that humans are ruining the world. Brightling orders the launching of a world-wide Shiva pandemic at the Olympic games in Sydney, Australia. Of course, his researchers have also developed a vaccine that will keep Brightling and his chosen few safe and alive.
