Moral behavior is an issue that a lot of parents have tremendous worry over. Really, you don't teach moral behavior, you demonstrate it. The best way for a parent to instill a moral compass in a child is to live a moral life themselves. The second best way is to make sure the child feels recognized. If you feel recognized, you will feel ownership in the family, the school, the town, whatever; and you will not be inclined to break the rules, because you will feel ownership in the group. You don't ever even have to have heard about the Ten Commandments. You don't have to have heard about the moral precept. You will simply be inclined not to do what you know is bad, because you have ownership in the group. Moral behavior, you learn through watching whatever your parents do; and feeling recognized by whatever group you are in.
