It shouldn't be that hard to believe. The reality is some people are born with biologically or structurally dysfunctional brains. Is it hard for you to believe that someone could be born with schizophrenia? What about autism? What about poor impulse control? When you think about the complicated interplay of social interaction in HEALTHY humans, which includes their innate capacity for violence (We definitely are part hunters with a propensity for war), and you compare the things we know that can go wrong and produce mental deficits of one form or another, it really shouldn't be that surprising that some people in the population would also be born with distinctly anti-social tendencies of one form or another. Brains are complicated... there's all kinds of interesting things that happen too that may be related. For example, the disgust response of humans is typically lessened or even reversed during sexual arousal. So you can have almost a complete flip in behavior depending on context! The regions of the brain responsible for aggression and sexual arousal are also really close together and related. So is this really that much of a stretch?
