To keep people and society in order. Otherwise, you have anarchy, which is bad (people doing anything and everything they want even if it hurts or kills other people or the earth).
To maintain peace,order,give people direction in life without the law imagine society,there would be no way to control crime we would be living as they did in what we know as the wild wild west,people would take the law into their own hands.....think about the laws,rules etc. In your home imagine what it would be like if there were no standards or rules set in your home....good luck
For the protection of people
In short, to protect the quality and integrity of the life you. To protect your dreams, aspirations. To protect society and allow the continued improvement of the Continental United States of America, the Greatest County on Earth
Laws and Rules are necessary in a society because if there was no rules and laws everything and every one would go crazy there would be fights and more gangs then these gangs now, but there would be more. People would get away from killing, and everything else.
Because people want law!!
