Fan Casting David Brightling in Zack Snyder's Rainbow Six

A billionaire pharmaceutical CEO with a warm smile and a messianic conviction that humanity is a virus destroying the planet. He quotes spinal fluid counts from memory, charms skeptical doctors, and genuinely believes engineering a global die-back of five billion people is "the right thing." When captured, the visionary mask slips to reveal a privileged coward hiding behind expensive lawyers. He's a bear who thinks he's a shark, a soulful monster whose eco-fascism is all the more chilling because he believes every word of it.
