This is silly sarcasm. A person in a brain-dead coma or in a vegetive state can't give consent. Just like they can't form a contract. That's when common sense needs to be applied. Doctors here have been doing it forever. Wake up. It ain't a bad thing.
parsy, the practical.
Yes, it is. This is not a decision for the doctors. It is a decision for the family or the pre-expressed will of the patient.
Of the euthanasia deaths, one-third of them were the result of doctors treating the symptoms of a disease or injury and just under a third involved doctors withholding treatment in cases when it is supposedly in the best interest of the patient
IOW, one third treating the symptoms (like pain, fever, nausea), but letting the patient die of the underlying disease, one third letting the patient just die. What is the remaining third? The only other option is actively causing the death of one who would not have died without intervention, and without consent. Doctor as judge, jury, and executioner.
