Do you believe all people are good, bad, or a mixture?

I've always been convinced we're all evil. Maybe it's just the way I've looked at things. Why do we have laws and why are we being watched? Why does it feel hard to do the right thing sometimes? If I am already born good, why would I need to train myself to do right? Did something throughout my life give me a reason to feel that all people are bad? How do you feel about people?
