WTF is wrong with some people?

"I'd like to share a revelation i've had, during my time here. It came to me when I was trying to classify your species, and it turns out your not actually mammals. Every mammal on this planet develops an equilibrium with its environment but you humans do not. You multiply and spread and consume every every natural resource, and the only way you can survive is to spread to another area.

There is another organism that follows the same path. Do you know what is it? A virus..... You humans are a disease, a cancer of this planet, you are a plauge. And we.... are the cure"
