This is the entire ethical basis of animal testing, except in this case, they’re at risk of actually helping the animals they’re testing. Compare that to e.g. malaria trials where they buy mice, infect them with malaria, and then see if the malaria responds. I’m a vegetarian because once I made the leap that animals probably have an internal experience, torturing and slaughtering them so my mouth can feel a certain way strikes me as not personally justifiable. How much worse is that? Should I go around calling everyone a monster? Hardly. Animal testing at least has some meaningful rationale, and testing treatments for diseases animals actually have seems solidly in the realm of ethically justifiable
