That is, it was nothing more than a typically narcissistic attempt to correct his image from that of cold-blooded psychopath to that of a poor, misunderstood serial killer. In other words, he does terrible things, he doesn't understand why does them, and needs help, sympathy and compassion. He will say or do anything to keep his mask firmly in place including the copious shedding of crocodile tears for his poor victims.
Dr. Robert Hare, Professor Emeritus at UBC, is Canada's internationally renown and foremost expert in the field of Psychopathy and has written numerous books on this topic as well as created the PCL scale which can be used to determine psychopathy in individuals.
According to Dr. Hare, in his book, The Disturbing World of the Psychopath:
"If crime is the job description, the psychopath is the perfect applicant."
Psychopaths are found in every segment of society, and there is a good chance that eventually you will have a painful or humiliating encounter with one. Your best defense is to understand the nature of these human predators."
"Psychopaths are social predators who charm, manipulate, and ruthlessly plow their way through life, leaving a broad trail of broken hearts, shattered expectations, and empty wallets. Completely lacking in conscience and in feelings for others, they selfishly take what they want and do as they please, violating social norms and expectations without the slightest sense of guilt or regret.
. . . psychopaths are generally well satisfied with themselves and with their inner landscape, bleak as it may seem to outside observers. They see nothing wrong with themselves, experience little personal distress, and find their behavior rational, rewarding, and satisfying; they never look back with regret or forward with concern. They perceive themselves as superior beings in a hostile, dog-eat-dog world in which others are competitors for power and resources. Psychopaths feel it is legitimate to manipulate and deceive others in order to obtain their “rights,” and their social interactions are planned to outmaneuver the malevolence they see in others."Psychopaths Among Us / Suffering Souls
