Edmund Pellegrino, MD, Director of the Center for Clinical Bioethics at Georgetown University, wrote in his chapter, "The False Promise of Beneficent Killing," that appeared in the 1998 book Regulating How We Die: The Ethical, Medical, and Legal Issues Surrounding Physician-Assisted Suicide:

“Euthanasia and assisted suicide are not ethical obligations of physicians… The prohibition against physician participation in euthanasia and assisted suicide has been elemental in the traditional ethics of medicine for a long time… These acts [euthanasia and assisted suicide] are far from being established morally or accepted professionally.”
