Interestingly I bet the kill thinkers killed fewer than the ad thinkers. Ads make people buy more stuff. More stuff makes people fat and unhealthy and sad and increase the mortality rate.
There is no MAD deterrence to limit advertising: only keeping up with the leader.
Once you've figured out how to efficiently kill most people on the planet, you can decrease investment in the endeavor and just keep a finger hovered over the button.
