Why is establishing justice important to our society?

Answer 1

Law and justice are important for civilized societies. Un-civilized societies not only breed chaos but "allow" people (no one's perfect) to "do whatever they feel like doing". But feelings are always temporary, and doing the wrong things based on "feelings" and not law, order, or respect for justice often have lasting effects not just on the person who broke the law but on others who are innocent. Laws are put on the books for a reason: To clearly let citizens know what the consequences are if broken. If there were no justice, there would be no reason for laws. The U.S. has an imperfect system, but it's up to individuals to make right decisions and they're usually made by thinking of other people first.
