One of the difficulties at present is that with the law the way it is, all the cases that are highlighted are the ones where people have suffered for the lack of a legal means of euthanasia. It's very hard to say what the other side of the coin might be like if the law were different.
I read a most moving article by a colleague of mine who had had to nurse his wife through pancreatic cancer. It was quite upsetting because I knew his wife too, but hadn't known she was ill. He described a final month where the best efforts of the palliative care team were ineffective, and Pauline was in severe pain and pleading to die. As a vet, Bob knew what to do and could have done it, and said it was only concern for the consequences for their children should he be convicted and jailed, that stopped him.
On the other hand, the mother of a friend of mine also had pancreatic cancer. I went with my friend to visit her in hospital on Christmas Eve (several years ago). She was bright and conversational - indeed, argumentative. She was a lifelong smoker, and defended her choice to smoke in the spirited way that had been typical of her personality. I could hardly believe she was as ill as I knew she was. Towards the end of the visit she asked the nurse for "another injection", and the nurse cheerfully obliged.
She died on Boxing Day.
It's so hard to predict how these things will go, and I don't know what the answer is. I do know that terminal euthanasia to spare someone the final painful days (in Pauline's case, Bob said it was about a month) would be much more likely to get my support if it could be guaranteed that it would only be used in extremis.
