As a scientist and fellow-vegan, I agree that doctors as individuals should be allowed to opt out of administering euthanasia if it goes against their conscience and that patients should be allowed to choose their doctor. Doctors are not obliged to perform abortions, and patients can choose a doctor who does (or doesn’t). But as surely as doctors should be free to decline to end sentient life if they wish, patients should be free to end their suffering if they wish. Vegans are against causing suffering and against ending life, but life is such that sometimes the two are in opposition. And personal belief in an afterlife is no excuse for imposing one’s hypothesis on others.
