Before getting into depth with this argument, it would be enlightening to define the terms euthanasia and assisted suicide.
Euthanasia is a broad term describing the intentional act of ending one’s life in order to relieve pain and suffering, whereas assisted suicide is a form of euthanasia where the doctor or physician assists the patient in their means of dying. However, I want to focus on assisted suicide in the terms of the physician assisting “end of life care”, NOT assisting in one’s death.
Euthanasia (in particular assisted suicide) is not about ending one’s life nor is it helping the patient end their life for nothing, for that shouldn’t be the motive. Instead, it aims to assist in relieving any pain and suffering in the events leading up to their death, preventing further suffering hadn’t the procedure been administered.
Euthanasia is to relieve anything that is detrimental to the patient’s well-being when dealing with an incurable illness.
