"When i do good, I feel bad. When i do bad, I feel bad''

This quote is saying that what you do explains how you are going to feel. What you do, whether its good or bad is going to make you feel good or bad.Some people do bad stuff and then later on they feel bad because of what they did. Or some people do good stuff and feel good about themselves. Whatever you do is going to express how you feel. Everyone will make mistakes or do good things to make someone else and their own selves feel either good or bad. If you choose something good then something good will come back to you. If you do something bad then something bad will come to you. It could maybe be a person you didn't like that you got in a argument but you went to apologize because you didn't feel good about all the stuff you said. Or you can steal from someone and then feel bad because it wasn't worth it.
