How heartless can they be? The delusion of dualism - me vs. all others - has so infected the psychopath class of 'murkan human artifacts that what Thom describes is the norm, and not the outlier. People are born with a set of genetic markers, inherited from past traumas that demanded strategies for protection from real or imaginary fears. Either via probabilities or the fresh set of traumatic experiences, these quickly set in motion the gene expressions of separation anxiety and fear-based paranoias, and the race to separate self from other is flying at warp speed. Our overworked cerebellums cannot begin to cope since they have no agency themselves, relying on the ancient and inadequate reptile brain to provide protection from real or imaginary dangers. No room for 'heart' in this equation.
