You are asking the question by accepting the assumption that euthanasia can be applied. But euthanasia has dimensions about health, law, morality, religious beliefs. Passive euthanasia is widely accepted. The main thing is whether active euthanasia can be applied. In the active euthanasia process, there is an understanding that will decision himself/herself if the patient does not lose his decision-making ability, also that in other cases his / her relatives should decide. Another approach is to make a will by means of "advanced directives" depending on the circumstance before losing the patient's decision-making ability.
I would instead prefer the palliative care option. However, if legal arrangements have been made, the euthanasia decision must be made that the patient by himself. If the patient cannot decide, then the patient's first-degree relatives can be given.
Euthanasia, mercy killing, is one of the counter examples to Emmanuel Kant's perception of morality. As Kant states , every individual should try his / her best to accomplish the task s/he is responsible for. However, in certain situations, the doctor ,whose duty is to care for a patient, decides to kill him/her to put an end to his/her agony. I believe that euthanasia is a logical way to help patients overcome their miserable state .
Hi Nader, I am interested by your question, or rather, why you ask it? "In a society where patients are routinely euthanized, whether they want to end their lives or not?" Why would we wish for a society that condoned such a thing? Euthanasia is a difficult subject with very strong opinions on all sides, but to ask who is responsible for legalised euthanasia where the person themselves do not want to die? Can you explain more?
The decision should come from the palliative care team and be approved by the patient him/herself. When a patient is incapable of making a decision his/her near relatives (Father, mother, son, daughter, grandson, granddaughter) could approve the decision.
I think the person who should make the call should be the patient themselves.. if patient is vegetative or incapable, you then have their parents or first child. Never spouses or next of kin. Because many times these people could make clouded decisions and/or many times biased decisions if there is a catch (such as inheritance, Insurance benefit, annuity plans etc)
