Are People Naturally Good or Bad

People today are good and bad but I believe that they are naturally good. I believe this because children learn from example and usually are good from the start with no impurities with in their mind. Naturally people are good but become corrupted with wants and needs dragging them down towards the bad side of people. I believe that people were evolved through evolution. Animals are innocent creature of nature, so, how can a creature be naturally bad? An innocent mind is a good mind and naturally humans are good.
