Creating the demand and the supply. It’s genius in a sociopathic way, but truly amoral. Maybe they could just clean up their own messes and we wouldn’t need the filters?

They both fit, but I did mean amoral which is a bit different. Someone who is immoral is breaking/doing something against their conscience, whereas someone who is amoral has no conscience.
