What is the impact of moral principles on the development of society and individuals?

Moral principles and norms (or foundations) have been formed in the minds of people for a very long time. For several centuries or even millennia. They influence a person very strongly. It should be noted that this influence is extremely positive. Personally, I cannot remember a single moral norm that badly influenced a person or society. Morality prescribes to be polite, modest, not to offend others, not to steal, not to offend, and so on. Unfortunately, today they are trying to violate the norms of morality. Permissiveness and shamelessness destroy the minds of young people. Therefore, one must always remember about the norms of morality and adhere to them. This will help a lot in life.
