Where does the evil in human nature come from?, Reivew on City of God

Is the evil side of human nature entirely due to the influence of the acquired environment? I doubted it after watching this movie. Xiaodouzi (the late Xiaobawang) at such a young age, it is so natural to take pleasure in murder. This may be related to the environment of his childhood, but more of it is probably his nature. Otherwise, how to explain that A Pao (photographer) still remains kind in the same environment.
After thinking about this, I also remembered the news that I saw a few days ago, the little girl elevator falling baby incident ( http://news.163.com/13/1204/23/9F9OVLLR00011229.html ). If someone is born to be evil, it really makes people shudder, because innate things can hardly be changed.
Also, this movie inspired me to continue learning photography. I studied for a while before, but recently let go of it.
