Hey Natalie. I like what you said about how he just wanted to see if it could be done. Part of me thinks that maybe he did not fully realize the ethics of what he was doing because he was just curious to see if he could even complete an experiment like this in the first place. As far as the Tuskegee experiment goes, I completely agree that that experiment is far more unethical than this twin HIV experiment. In the Tuskegee experiment there were deaths that could have been fully prevented using the penicillin syphilis cure, whereas currently there are not side effects to that degree in the twin HIV experiment. That's not to say there could be in the future, but with the knowledge that we currently have it is reasonable to conclude that this experiment, while unethical, is not nearly as unethical as the Tuskegee experiment.
