The practice of euthanasia is often linked or put in opposition to palliative care as both concern themselves with the well-being of terminally ill patients. There is no consensus in the hospice community on the legalization of euthanasia.
Euthanasia cannot be undone. If the main reason for the legalization of euthanasia is alleviating the pain of a terminally ill patient, then the administration of opiates or other pharmacological measures aimed at minimizing suffering reach that goal. There’s no justification for ending a patient’s life. Administration of anesthetic is always preferable to euthanasia since it doesn't create ethical dilemmas, doesn't put a responsibility of deciding in matters of life and death on physicians, and keeps the possibility of recovery open.
There are diseases and conditions for which palliative care is not a viable alternative. Palliative care cannot stop some patients from experiencing constant vomiting, breathlessness or paralyzation. Palliative care also does not resolve the issue of patients' dependency on others.
[P1] The goal of the euthanasia is alleviating the pain of a terminally ill patient. [P2] Palliative care can reach that goal without ending a patient's life. [P3] Therefore, the palliative care is always preferable to euthanasia.
