I think that moral status once determined is unchanging unless someone’s mental capacity changes. If I went into a coma tomorrow then my moral status would change because I would not longer be able to make decisions as a moral agent. I would also lose the ability to suffer and to reason which are qualities that would make me a moral patient. It is possible that people in a coma, especially if they are not expected to come out of it, do not have moral status. They did when they were conscious, but they have lost it. Children’s moral status also changes. They begin as moral patients because they are unable to make choices for themselves, but they become moral agents as they mature and can handle personal responsibility. Somebody with a mental illness that incapacitates them could change their status if they went on drugs that allowed them to control their condition better. I think that unless one’s ability to suffer or to reason changes their moral status will not change. I am reluctant to say that one’s moral status changes if they commit a crime. Our respect for them changes as do their rights and freedoms but this is due to consequences of actions. A moral agent has a responsibility to act morally. We would not say that a child or non-human should be punished for actions in the same way as an adult human because they are not moral agents.
Should people in a coma that are not expected to recover have moral status?
