I wonder whether AB has discussed with his family and made it clear what he wants to happen at the end of his life, and whether he has taken steps to register a legal document that can allow his family to override medical wishes if he is unable to state them himself, etc. I wonder how much of the final moments of his life he leaves to God, how much to medical staff, and on what grounds he bases that decision, etc. He might then - although highly unlikely - re-evaluate his stance on a person's right to decide.
