The morality of compromise sounds contradictory. Compromise is usually a sign of weakness, or an admission of defeat. Strong men don't compromise, it is said, and principles should never be compromised
A compromise creates a win win situation, because both parties give something up but each also gets something that they want in exchange for their sacrifice. In life it is necessary to compromise on many things, but the one thing that should never be compromised is integrity. The concept behind this idea is that there has to be give and take from both parties in order to reach a middle ground and mutual agreement.
