A sad tale made even sadder...

Here's the situation - a devoted married couple, both in their 80's, are in poor and worsening health. They decide to go out together by both taking a drug overdose. When they are discovered, the husband is dead, but the wife is still alive, though only just. She is rushed to hospital where the medical staff do all they can to save her. Why??? What possible good can come of it? If she survives, she will be faced with the same health problems as before - if not worse - and without the husband she loved and who supported her. How cruel is that? Did anyone for one moment consider what she would have wanted?
