Do you think they were born like that? Have you never done anything wicked in your entire life? I view that type of behaviour as not everything-or-nothing matter, but rather as a spectrum. Imagine those "sociopaths" as adults changed radically and became role models. Who are you to judge people based on the actions they did when they were probably still children, developing and probably being attacked themselves? Do you think that you are free from sociopathy? Imagine your parents raised you in a cage, sexually abused you everyday and beat you? Do you think that that would affect your personality in any way? Do you think it would somewhat desensitise you from other people's pain?
