That doesn't make any sense. You treat a human being as one entity and a whole animal species as one entity. Almost nobody would see any problem with killing a particular wolf that repeatedly attacks people.

Diseases that are part of erradication programs used to kill or cause lifelong disability to millions. Diseases that kill thousands could be recommended to vaccinate aginst for those at risk. There would hardly be any research into a disease that kills 10 people a year.
