Criticism
Common use of the term is criticized by scholar Gregory S. Kavka in Journal of Business Ethics. Kavka refers to philosophical concepts of retribution by Thomas Hobbes. He states that if something supposedly held up as a moral standard or common social rule is violated enough in society, an individual or group within society can break that standard or rule as well by being being unfairly disadvantaged. As well, in specific circumstances violations of social rules can be defensible if done as direct responses to other violations.

For example, Kavka states that it is wrong to deprive someone of their property but it is right to take property back from a criminal who took  another's property in the first place. He also states that one should be careful not to use this ambiguity as an excuse to violate ethical rules recklessly.

Conservative journalist Victor Lasky wrote in his book It Didn't Start With Watergate that while "two wrongs don't make a right." if a set of immoral things are done and not prosecuted, that creates a legal precedent. People who do the same wrongs in the future should thus rationally expect to get away as well. Lasky analogizes the situation between John F. Kennedy's wiretapping of Martin Luther King, Jr., which led to nothing, and Richard Nixon's actions in Watergate, which Nixon thought would also lead to nothing.It Didn't Start With Watergate. Victor Lasky.
