It seems that there's a neurological basis underpinning their mental disorder:
The brains of psychopathic violent criminals have abnormalities in regions related to punishment that are not seen in the brains of violent criminals who are not psychopathic, according to new research using brain scans.
These MRI scans suggest that psychopaths don't grasp punishment the same way as other people, the researchers said. This is likely why psychopaths do not benefit from rehabilitation programs, as other violent criminals often do, the scientists report today (Jan. 28) in the journal Lancet Psychiatry.
In the group of criminals who were psychopathic, the scientists observed lower volumes of gray matter in brain regions involved in empathy, moral reasoning, and the processing of social emotions such as guilt and embarrassment. They also found abnormalities in white matter fibers leading to the prefrontal cortex, in regions involved in learning from reward and punishment.
Those with psychopathy are less empathetic, more callous, more manipulative.
That seems to describe Leftists to the letter; they claim to be looking out for the interests of the very people they consistently screw, but because they're so manipulative, those folks believe that they really are on their side. Interestingly, after decades of this sort of manipulation, blacks are increasingly waking up to the fact that they've fallen out of favor, as the Left goes after the Latinos.
Were it not sad, it would be amusing.
