There is a standard of behavior set in the universe and all of us try to follow it and when someone breaks it the effected human is the man who tries to prove that he is the right and other one is wrong. Every man tries to follow a standard of right and wrong in the universe and when he breaks that standard he always have some reason for it and tries to prove himself right through the reason e.g. a footballer can never foul until the rules of the games are clear.Augustine of Hippo,a great philosopher says that,“Right is right even if no one is doing it; wrong is wrong even if everyone is doing it.” 

                                  The law to prove right and wrong is actually the law of nature. People when think nowadays about law of nature they think it as a law of science. In the past when someone talked about the nature he meant the human behavior. They called it so because they knew that every human being knew it and did not need to be taught it.

                                      Some people say that different civilization have different values are right up to some extent but actually there are some values which are same everywhere e.g. running away from a battle is admired nowhere or double crossing the people kindest to them is a wrong thing anywhere. 2+2 is never 5 but 4 always. If anyone says that he do not believe it he rejects himself his saying by his action very shortly.

                             Actually no one in the world follows really the law of nature and if you say him he always has a lot of reasons. If someone becomes angry the if you ask him, may that he is tired or many more explanations at once. We never accept our mistake and always want to get the credit of success. In short we all break the law of nature that we all know  and this is all clear thinking about ourselves and the universe that we live in.
