An elderly man, James, is murdered. During the autopsy, doctors discover that James was HIV-positive for over twenty years but never developed AIDS, suggesting that he had some kind of genetic resistance to it. Studying his body might yield information that could lead to a cure, vaccine, or new treatment for the disease. James’ family, however, refuses to grant permission for his body to be used for medical research, will not change their mind, and evidence exists that James himself would not have consented to such research either. Using one and only one of the following theories (Confucianism, Yangism, Mohism, or Daoism), determine what is the morally correct thing for the doctors to do in this situation.
