Morals are what you believe to be right and wrong. People can have different morals: you might say, "I like his morals" or "I wonder about his morals."
Your morals are your ideas about right and wrong, especially how you should act and treat other people. Most people would agree that thieves, murderers, and other criminals are lacking morals. A lot of people would say politicians could use some morals as well. Every person has a slightly different set of morals, and different cultures have their own morals as well. You probably get your morals from a combination of your parents, your teachers, your culture, and your religion.
