Honestly, this theory really isn’t that crazy.Na, na the guy has a receive gene of psychopathy inherited from his father who was also a psychopath, the difference is that his father lived in times of war, so his violence and rape were validated and encouraged by his job, his son however lived under caring families but was also a psychopath so his behavior was now a problem, killing, pillaging, and raping were now not desirable traits, what allowed his father to excel as a soldier, was now getting the son in trouble.
