Euthanasia vs Life Support
Several governments around the world have legalized voluntary euthanasia.
In Russia, euthanasia is banned.
In 2002, The Netherlands legalized euthanasia including physician assisted suicide.
In Mexico, active euthanasia is illegal but since 7 January 2008, the law allows the terminally ill - or closest relatives, if unconscious - to refuse medication or further medical treatment to extend life, in Mexico City, Aguascalientes and Michoacan.
I believe that euthanasia is unethical until a certain point. If the person is not conscious or does not want to be "disconnected" then it is unethical. But if the person does not want the family to be wasting the money on them, then it should be the person's call. Nevertheless, nobody can take away someone else's life that is not God.
