comparison on New law purpose with old law purpose?

Question

Law everywhere shares its old purpose: to free life from arbitrary, or merely random, action and decision, and provide redress against them. That can mean conviction of burglars, recompense for injury, protection from fraudsters or from governments, witness the growing use of judicial review to challenge official action in those very countries where lawyer is becoming a rude, if well-rewarded, word.

Is this only purpose of law

Answer 1

In the US, the purpose is defined in the Constitution of the United States preamble. I believe that all US laws derive their authority and purpose from these

1. establish Justice
2. insure domestic tranquillity
3. provide for the common defense
4 promote the general welfare
5 secure the blessing of liberty to ourselves and our posterity

Answer 2

"LAW" is a derivative of simple natural logic amalgamated with the life style of the people of that area, their habits, culture and the social myths etc. It is progressive thing also. In changing lifestyles the amendments in the laws are done. Depending upon the above every country has formulated their own law. If the people of the country do not have any dispute among themselves there is no sense of using any law. Law is the principles/guidelines on which the disputes are to be solved between two person.
Now, the second aspect of the question is about the implementation of the law. It depends upon the leadership of the country. In democratic countries, for everything the verdict of the people is required where as in countries which is rules by a dictator / dictator party it is the decision of the Govt. which is final and binding on the people of that country. So only in democratic countries the face of the law can be seen as depicted in the question.
