APAD: All is fair in love and war

 All is fair in love and war.

One can break the rules of fair play under extenuating circumstances.

Example: In the face of cutthroat competition, some companies adopt unfair practices. To them, it seems all is fair in love and war.

 

Like you can't reason in  the families, you can't critisize the doings of any parts during war times. Winners have the right to speak.
