all is fair in love and war
1
used to imply that in certain situations, such as relationships or conflicts, people may be willing to take any action to achieve their goals, even if it is not morally or ethically right
The origin of the proverb "all is fair in love and war" can be traced back to the 16th century, where it was first used in literature, notably by John Lyly in his work 'Euphues' in 1578. The proverb reflects the idea that emotions and intense situations, like romance or war, can blur the lines of acceptable behavior. It serves as a reminder that, while such situations might justify extreme actions in some people's minds, the ethical consequences of those actions should still be considered.
