But it's not you that's killing the test subjects; they're doing it to themselves. (Well, it depends on the experimental setup, but it can be easily arranged that way: you could leave a spray bottle on the table and tell them "This contains the coronavirus. If you spray your face with it, you will help our experiment, but risk death. You are also free to just go home and face no consequences.") I don't understand the argument for moral relevance.
