As a generalization with no knowledge other than my cursory reading, it sounds like some evil creep had a "Dr. Evil" idea one morning, a sort of evil enlightenment after AIDS came up a bit short and SARS didn't do enough damage. An evil epiphany, followed by a ghoulish laugh -- sort of like "The Grinch Who Stole Christmas."
He felt remorse that AIDS is only by blood and SARS is only by air, and why not give AIDS wings? Sort of like rats aren't bad enough but give them some wings and make bats.
So, he and his team accomplish their goal and now they start to not trust each other on the team and kill the evidence and kill each other.
Possibly they were pawns directed by evil superiors who convinced them it was for the good of the state or mankind in general.
Oftentimes when one can no longer compete legitimately in creating avenues to further humanity, for the benefit of mankind, they take the opposite road and achieve success in treachery and fulfill their ego by achieving demonic heights.
