Euthanasia and assisted suicide in their various forms remain a heated and polarising debate. There is global variance in the legalisation of forms of assisted dying; with it being legalized in some form in some countries, and staunchly prohibited in others. As legal status varies from country to country, so do religious and social views; within some countries, there is entrenched opposition to the premise of assisted dying, whereas in others it has become increasingly socially acceptable; and in some countries generalised acceptance of euthanasia is the majority viewpoint. Religious and historical perspectives can be used as a lens to explain and understand these varying social views. This chapter provides the religious, historical, legal, and ethical perspectives related to assisted dying.
