The thing is that everybody has a different point of view about clinging into life or being allowed to die. One size doesn't fit all. If life has become intolerable then under a very strict criteria, if that person wishes, then helping them to die peacefully and with dignity, is, imo both acceptable and humane. My stepfather had terminal cancer, my mother died suddenly in her sleep, he suffered badly both emotionally and physically, it was a terrible time for him, and we were helpless to help him. I still, 37 years later, can't think about it without tearing up. When he was dying, he told me not to be sad because that was what he had been looking forward to since my mother had died. He also thanked me and DH for all the care and love we had shown him. Should be have been able to die peacefully sooner? On balance I think yes. However, it is a difficult one!
