From Wikipedia, the free encyclopedia
In rhetoric and ethics, "two wrongs don't make a right" and "two wrongs make a right" are phrases that denote philosophical norms. "Two wrongs make a right" has been considered as a fallacy of relevance, in which an allegation of wrongdoing is countered with a similar allegation. Its antithesis, "two wrongs don't make a right", is a proverb used to rebuke or renounce wrongful conduct as a response to another's transgression. "Two wrongs make a right" is considered "one of the most common fallacies in Western philosophy".[1]

History
The phrase "two wrongs infer one right" appears in a poem dated to 1734, published in The London Magazine.[2]

This is an informal fallacy that occurs when assuming that, if one wrong is committed, then another wrong will cancel it out.
