Why do people try to impose "fairness" on life?

A good question. What is a life ? we born free and go free. nothing we brought and nothing we take. Anyone can live on his own means the same will not be a life. we follow freedom in some angles and we follow some rules in some cases. To a disciplined life we have to follow certain rules in the form of guidance. After all, the rules are for a good way and disciplined life. If we ask someone not to go, they will see us wonderfully, and if we say that there is a rule or law, they will oblige. In this angle, we impose fairness on life. why law? and what is a law ? Law is a rule purely imposed on mankind for a disciplined life and also needed to a country. if you take a domestic inquiry, where fairness is imposed to arrive to a conclusion of the findings to prove beyond reasonable doubts. Without a fairness how can one arrive to a decision or conclusion. The fairness is imposed here to arrive a decision. simple method of fairness is the rule of traffic regulation. we can not drive car straightaway and certain rules are imposed on us. when there is a red signal, we have to stop driving, and for green signal we can continue driving. Here too fairness imposed on life for averting something. so, the people try to impose fairness for professional responsibility, and the law makes way. while we purchase a doll or stone carve, we imagined the same on seeing somewhere and we select the one which have the fairness and we impose the fairness on shop owner. Here we are people. we have certain commitments in life. For fulfilling commitments fairness is a must. so, people try to impose fairness on life is for us and for a good life means a disciplined life with rules of law.
