If we all were then there would be no distinction of what a psychopath is. A psychopath is a point of interest in human society because they do not feel empathy, do not have the same level of emotionality that "normal" people have. By not having empathy they have different strengths and weaknesses, but what is most interesting is when you evaluate how positions of power are mostly occupied by them. To really delve into this and then actually come to terms with this is what this study, and author should further evaluate.
