Ezekiel Emanuel wrote in The Atlantic Monthly in 1997:
The proper policy, in my view, should be to affirm the status of physician-assisted suicide and euthanasia as illegal. In so doing we would affirm that as a society we condemn ending a patient's life and do not consider that to have one's life ended by a doctor is a right. This does not mean we deny that in exceptional cases interventions are appropriate, as acts of desperation when all other elements of treatment -- all medications, surgical procedures, psychotherapy, spiritual care, and so on -- have been tried. Physician-assisted suicide and euthanasia should not be performed simply because a patient is depressed, tired of life, worried about being a burden, or worried about being dependent. All these may be signs that not every effort has yet been made.
Medical ethics is a complex discipline, but Emanuel was at every step on the record in opposition to even voluntary euthanasia and physician-assisted suicide.
