When and how forcefully must we intervene to save a life, and when should we respect the will to die? This book presents alternative ethical paradigms to understand contemporary challenges in suicide research, prevention, practices, and policies, including challenges in the expanding legalization of euthanasia and assisted suicide ('medical assistance in dying'). Drawing on case studies and philosophical approaches, analysis focuses on decision-making when we are faced with questions about obligations to help and intervene in suicidal situations. Chapters cover moral dilemmas in rescue policies, ethical challenges in suicide research, civil and legal considerations, and similarities and differences with accessing medical assistance in dying. Discussion is grounded in contemporary debates, addressing important issues such as if we should continue to hospitalize people to protect them from self-harm, or control access to 'dangerous' suicide content online? This book is unique in its focus on the practical concerns of mental health professionals, helplines, researchers, policy makers, and programme planners who are faced with ethical challenges in suicidology and suicide prevention.
