Two bioethicists ? one from Duke University, the other from the National Institute of Health ? bring up the question "What makes killing wrong?" in the latest issue of the Journal of Medical Ethics. Using their definition of killing, the authors conclude if the person is "universally and irreversibly disabled" and has "no abilities to lose" then killing them to take organs for donation in order to save the lives of others should not be considered morally wrong.
