Whenever you violate a principle, you get a short-term gain, but a long-term loss.
Calculating principles & goals must also be done with other things beyond numbers. Sometimes a short-cut is just a short-cut but there are other times that it is not & we are robing from either ourselves or ourselves & others. Rules, boundaries, guidelines, and even commandments are most often given to protect us. Values such as integrity, respect, reliability, honesty, and obedience are meant to be pure and not mocked or slighted.
As most parents & teachers would say, "think before you speak" or "think before you act." Think about what the effect will be or what the consequences will be toward your actions and as I say, "Be good," or "Play Nice!"
