A ruler in society is responsible for creating rules and regulations for society. Also I think ruler is responsible for  society's rights, and how to make it's society happy and wealthy. The ruler has to just the society. I think people are not naturally born with good or bad. These things people learn as they get older and learn. Also they learn from their parents and family who take care of them and teach them. In my opinion the government should control the taxes and economy. A society is just by law and equal rights. Everyone has to follow the law and that makes society just. Also equal rights are very important in ruling the society.
