High Quality Content by WIKIPEDIA articles! The abuse defense is a criminal law defense in which the defendant argues that a prior history of abuse justifies violent retaliation. While the term most often refers to instances of child abuse or sexual assault, it also refers more generally to any attempt by the defense to use a syndrome or societal condition to deflect responsibility away from the defendant. Sometimes the concept is referred to as the abuse excuse, in particular by the critics of the idea that guilty people may use past victimization to diminish the responsibility for their crimes.
