What is your idea about doing right and wrong things? Say what you must and mustn't do

People usually do wrong things. There are many reasons why they act like that. People, doing wrong things, usually considered to be bad people. They can be thieves, murderers, not kind and not polite people.  They can easily insult everybody and do not have respect toward others. But not always people do wrong things. They also can do right things. I think, everybody must be at first kind, polite and have respect. They must not insult other people, they must not say bad things and they must help the others.
