Atonement

Atonement (also atoning, to atone) is the concept of a person taking action to correct previous wrongdoing on their part, either through direct action to undo the consequences of that act, equivalent action to do good for others, or some other expression of feelings of remorse. From the Middle English "attone" or "atoon" ("agreed", literally "at one"), now meaning to be "at one", in harmony, with someone. Atonement "is closely associated to forgiveness, reconciliation, sorrow, remorse, repentance, reparation, and guilt". It can be seen as a necessary step on a path to redemption.
In law and society.
In the legal systems, the concept of atonement plays an important role with respect to criminal justice, where it is considered one of the primary goals of criminal rehabilitation. One philosopher has proposed that there should be an "ethics of atonement", and that atonement is an underrepresented area of study in philosophy and a topic given absurd treatment in the arts.
In religion and behavior.
In religion, atonement is "a spiritual concept which has been studied since time immemorial in Biblical and Kabbalistic texts", while "[s]tories of atonement are ubiquitous in religious discourse and the language of atonement fundamentally reveals a redemptive turn".
Concepts in religion include:
Concepts of atonement also exist in other religious views. For example, in Native American and Mestizo cultures of the Americas, "[s]ince sin and guilt are among the principal causes of illness and maladjustment... confession, atonement, and absolution are frequent rituals used in treatment. In some cases, atonement is accomplished through prayer or penance; in others, it may involve cleansing the body, accomplished by brushing the body with branches of rosemary or by sprinkling it with holy water".
Concepts of universal atonement can transcend all religions, as in unlimited atonement, the doctrine that the atonement is unlimited in extent, and universal reconciliation, the doctrine that all will eventually come to salvation.
Twelve-step programs include an atonement or "making amends" phase (steps 8 and 9). Tobby Fried asserts that this associates with restoring what she calls "integrity".
