I like the idea of death with dignity. If it is the brain/mind that is causing someone unimaginable suffering with no chance of repair, but the individual's other organs are functioning, why can't we discard that brain and use his/her organs for organ transplants? There are no brain transplants, but if someone has a functional brain and a liver that is killing them, why not let them have the healthy liver of someone whose brain is irreparable? Right now, if one is in a long-term coma without consciousness and cannot make the choice, this is possible, but if someone is conscious, capable of stating a choice, and begging "please, no more", it is forbidden.
