Morals, is the right answer.

Explanation:

Morals are a collection of rules, principles, beliefs, values and customs that supervise the conduct of people in a community. It enables people and organisations to recognize which actions are safe and which are harmful to culture. It is somehow different from ethics to the extent that ethics is the systematic investigation of moral systems to find universal or undeniable ethical systems. In contrast, morality places different values for good and evil depending on the social, cultural and historical context.
