I agree with all you've said slimboyfat. There is definitely some sort of psychopathy going on here. I'm definitely shifting from what I thought was sociopathic the psychopathic narcissistic behavior. He knows EXACTLY what he is doing, but lacks any empathy or moral compass to even feel the slightest remorse to his actions.
The very reason people get so frustrated (with good reason) regarding his actions who have normal human emotions such as empathy cannot comprehend how a person who cannot experience such emotional traits can be so callus. In his mind it is normal.
The bad news is, those who display psychopathic narcissistic behaviors are not curable. In order to get to that point one needs to understand that they have a problem and reflect. They simply have no capability to reflect.
Lloyd would be a perfect study subject on the nature verses nurture theory and how learned behavior can affect an individual in adulthood.
