Why is it important to become a good person?

It's important to become a good person, because we have to know how to treat people well, so we can have good relationships with everyone else, because, usually, people don't like to mix with bad people, since they don't treat them well, they hurt them, and they don't care about them. Ever since I can remember, everyone had teach me a lot of things, so I would become a good person. People like my family, teachers, TV (It actually does) and even friends. All these people have influenced me to become a good person, and I'm sure every single person has been educated the same way, although some people, for different reasons, become bad people.
There are a lot of bad people in the world, and no one can deny that. These are the people that kill other people, rob them, are bad influences, and even the people who lie to make people look bad, like saying a person did something bad, when in fact the person never did.

If we have a friend that is acting like a bad person, we have to help him, so he can become in a good person, because if he doesn't, as previously stated, he can hurt the people around him. And if our efforts are useless, we'll have to stay away from him, as he might become a bad influence for yourself.
