Recently, there have been doctors in Taiwan who are actively promoting fasting for a better death. The promoters believe that they cannot bear the suffering of all beings, so they help some patients stop eating at home, speeding up the death of patients, and ending the unbearable physical and mental pain of patients. The more controversial case of not giving patients food is that some demented elderly people who can eat by mouth, but do not want food, are deliberately and planned to gradually reduce their feeding to make their bodies exhausted, and then ask the palliative team to take care of them. However, this approach conflicts with the concept of palliative care, which emphasizes the principle of comfortable care without shortening the patient's survival. The active promotion of fasting and a good death has also sparked many ethical controversies. This article discusses fasting and a good death from the perspective of Buddhism, as well as the relationship between the two, and then discusses whether it is appropriate to promote fasting and a good death from the perspective of Buddhism in the advanced and final stages of illness. Fasting does not necessarily lead to a good death, and a good death does not necessarily require fasting. Whether to fast at the end of the period should depend on the physical condition and the patient's own decision, and family members cannot decide whether to fast or not. Promoting fasting to death can lead to a good death. This is called lamenting death and honoring death in Buddhism. Praising death is good. Avoiding suffering in the world by dying early is not supported by the Buddha's teachings.
