In April 2016, a tragedy occurred in the Netherlands, the country where the world’s first euthanasia was legalized. This tragedy shocked the whole society and seriously affected the beliefs of doctors who were willing to assist in the execution of euthanasia. A 74-year-old woman with Alzheimer's disease suddenly reacted strongly during the euthanasia. However, with the assistance of the family physician who was ultimately responsible for the implementation, regardless of the party's resistance, the drug was still injected and subsequently died. On November 9, 2018, the Dutch public prosecutor prosecuted the female physician responsible for the euthanasia on the grounds of overpower. This case strongly shakes the will of the death physicians from all over the world. Meanwhile, if the patient's autonomy is inconsistent before and after, how should we respond? It will be reviewed more deeply. This article begins with the case of the old woman who is forced to complete euthanasia in the Netherlands, proposes three doubts about respecting autonomy, and secondly analyzes the relevant cases to point out the controversies behind these doubts. Finally, this paper puts forward the viewpoints and suggestions.
