I tend to agree. We are all born selfish due in part to evolutionary biology. Becoming less selfish, and more selfless begins with good parenting and a fairly painless evolution to adulthood (something our society so often seems organised to suppress). Then with age, and maturity, and learning lessons from the life of hard knocks, all social relationships and interaction, and introspection on the kind of person we want to be - we have the potential to become fairly selfless creatures.
That said I believe there is a dark side in all of us, often loosely referred to as the reptilian brain: When anomie, and accidie collide all sorts of horrors can ensue, where one might descend into psychopathy temporarily and commit what 'civilised' society deem to be evil acts, crimes against humanity, ethnic cleansing, war crimes etc.
At the societal level we can see that the most civilised of societies can descend into war and barbarity.
Does evil exist in some metaphysical, Zoroastrian sense? I do not think so, but would not exclude the possibility.
Are there any inherently evil persons, or acts? I tend to think not though in certain cases the enormity of the crime, and the remorselessness of the criminal certainly can create the illusion of inherent evil.
I think the study of schizophrenia, delusional disorders and other psychiatric research may give us answers to one's propensity to selfishness, idiopathic psychopathy and sociopathic tendencies.
