Another reason for my opposing euthanasia is that is severely adverse to the professional ethnics of doctors. No matter how intolerable the patients’ pain is, they have no right to put their patient’s life to sleep. According to the Hippocrates Oath, all doctors have pledged to treat the ill to the best of their capability . Indeed, some patients who is in the coma still have a chance to survive or at least extend their lives a little longer by alternative or herbal medicines. I used to see my middle-aged neighbour use the herbs to completely cure his cancer within five years.
