It shouldn't. Euthanasia is ILLEGAL in this country
Are all the people who authorize this for one of their loved ones murderers?
If their loved one died of starvation and dehydration, yes. Surely you can see that. It's very simple. If they would not have died otherwise, yes, those people are guilty of causing their deaths. They can tell themselves they were "letting them go" or "setting them free", but I don't have to participate in their fantasies or word games.
Again, euthanasia is ILLEGAL. We've got Dr. Kevorkian and a number of "angel of mercy" killers in PRISON for hurrying sick folks out of life before their time. In view of the fact that families are killing other family members by witholding nutrition, should we just let all the convicted go free?
It's not euthanasia anymore than disconnectinga respirator is. It is withdrawing the medical measures that are keeping a person alive. If that person, or their representative declares they do not want life supporting measures, who are the rest of us to judge them. People need to get a grip and look at this from the standpoint of the dying who do not wish to be sustained in this manner. Why should they be kept alive against their will?
