I'm not at all surprised by the article, I'm sure this happens around the world with a much greater frequency than people might realize. I think it's pretty sad that a terminally ill, miserable person can be forced to continue enduring their personal agony against their own wishes. Sometimes I think people are more concerned with their own conscience than the patient's wishes.
I took Ethics as part of my philosophy curriculum in college, and I actually debated euthanasia and assisted suicide. I think, like a few people have said, that in certain situations the lines can become blurry. Plenty of people can get on board with passive euthanasia, ie. withholding of care, but not with active euthanasia--an actual action being taken to induce death, such as an intentional overdose. And plenty of people can accept it for terminal patients, but under what qualifications? A year left to die? Six months? What about chronic, intractable pain? There are people who live in agony every day who, while they are not dying, probably would welcome death if given the opportunity. Personally, I don't think it's my or anyone else's business to tell a person when or how they should be able to check out. I'm only 26, but I have told my parents and my lawyer about my end of life wishes. Definitely something to take care of because we never know when it may be our time, especially given this game so many of us play.
