Imagine a deadly scenario like this: a successful businessman is rendered unconscious by medical professionals to help him heal after a serious car accident, using powerful pharmaceutical agents to cause a medically-induced coma.
A few days later, a business competitor, wanting him dead, enters the hospital and kills the comatose patient. During his trial, when questioned about the murder, the competitor tries to argue, with an unnecessarily detailed explanation, that, “the medically-induced coma rendered him quite incapable of feeling any pain, because those parts of his brain involved in sensory processing and pain perception were clearly decoupled from consciousness. So killing those who are unconscious, at least on the grounds that they might feel pain, should not be seen as problematic nor should it be restricted as a personal choice.”
