It is often assumed that wrongdoing can only be resolved through punishment or forgiveness. But this book explores the responses that wrongdoers can and should make to their own misdeeds, responses such as apology, repentance, reparations, and self-punishment. It examines the possibility of atonement in a broad spectrum of contexts -- from cases of relatively minor wrongs in personal relationships, to crimes, to the historical injustices of our political and religious communities. It argues that wrongdoers often have the ability to earn redemption within the moral community, that respect and trust among victims, communities and wrongdoers can be rebuilt, and that the moral responsibility of wrongdoing groups can be addressed without treating their members unfairly.
