It's a lunatic position. Consider the die-hard environmental activist who decides the best way to save the planet is to create a collection of deadly infectious pathogens, distribute them to every major city on the planet, and so reduce the human population by 75%, creating a glorious utopia for everyone to enjoy.

Several books and movies have employed this plot, 'Cobra Event' comes to mind.

Consider the psychology of the megalomaniacal individual who knows what's best for everyone based on their own personal views and experiences, who takes no input from anyone else, because everyone else in the room is an idiot who doesn't understand the genius of their position...

This might lead to arguments like "who's more of a lunatic, the woman who releases the virus that ends the insane human population explosion on Planet Earth, or the woman who doesn't? I'd argue the latter."

To quote William Gibson, roughly: "It's like they're all running around with luminous messages scrawled on the inside of their foreheads."
