Excuse me for interrupting. You mention that it is telling patients that it is useless for them to fight for their life. But they are in a situation where the process of death has already begun and is irreversible. Hopefully, the dying person is in an optimal palliative care setting; that would be the ideal situation.
Since palliative care is the optimal support for human beings as they move towards death, why would a request to die that comes from an optimal palliative care setting be considered a failure rather than a success? From the moment that a human being is ready, one morning, serenely, to let go, why would that not be a success for the support palliative care provides as death approaches?
