I'm sorry you were downvoted for asking that. I think it's a fair issue to raise. Assuming the mice are intentionally injured to allow testing, it seems reasonable, to me, to question the ethics of that. Of course it's easy to say "they're just mice, who cares?" but it's not wrong to ask "they're living creatures as well, shouldn't we care?" I expect the response to be "it's justified given the benefits we derive for humans, based on this mouse based research", and probably most people would agree with that. But perhaps not everyone would.
Also consider the number of really scary books/movies out there rooted in the idea of "medical utilitarianism." For one example, this issue is addressed in a show called Biohackers that I just started watching. And even in real life, people have tried to justify a lot of really sketchy stuff over the years, in the name of "the greater good".
