Worse than this, there are some doctors who would ignore a properly executed advance directive and go with the family wishes even if they family admits that is not what the patient would want. I think it is very sad that someone can have their wishes disrespected in such a manner.
Have seen the same happen with organ donation and it just kills me.
People's willingness to betray the wishes of others in what I can only assume to be an attempt to force their own personal opinion to win out is saddening indeed.
