Doctors cannot play god. Live or die are not at the hands of the doctors.
It is normal procedure to transfer between wards when current situation permits and your case is not isolated. I lost a grandmother exactly the same way, somehow you need to learn how to let go and come with the terms. The government hospitals and staffs are doing the best to serve the public and not just your family. They are understaffed, working long hours with high patient rate and now has to deal with nonsense like you.
