"Good" and "evil" are a religious dualism not found very often in nature. We are all born to survive. Some methods of survival are pro-social and life-affirming, others are destructive and self-serving.
Many of us do have an ability to grow and recognise the value of pro-social behaviour. Some are raised to be anti-social. Some are born with something seriously wrong with their heads that cannot be reached by any amount of good training or persuasion.
Our culture is designed to breed narcissists. Capitalism has proven an exceptional tool for propping up systems of hierarchy. We are never allowed to feel good enough, and we are forever chasing after being special.
