psychopathic tendencies are genetic and present from birth. However, the sadism is learned.
in my opinion, sadism can only be learned as a young child via by close observation of a sadist. usually the child is the victim and the sadist is a parent. when this occurs as the fear center is developing, the ability of the child to sense 'emotions' in others allows him to see the parent deriving pleasure through the child's pain (parent is a sadist), and I believe that this causes the developing fear center to be 'rewired' in the child such that it triggers the pleasure center instead of the humor center which is what 'should' be triggered in those with 'standard fear center disorder' (psychopathic tendency but lacking sadistic urges).
a psychopath without the sadism may have little problem navigating society, and may live a comfortable life using his skills in service to a corporate master.
just a hypothesis.
some evidence:
"Positive pictures included images such as happy couples, puppies, food such as ice cream, and others. Neutral images included, for example, buildings, a black book, and a fork. Negative pictures included threatening animals or faces, heavily wounded persons, and skull and bones...
Prefrontal regions are directly connected with subcortical structures of the limbic system (Damasio et al 2000). In this neural circuit, frontal regions are supposed to modulate or inhibit amygdala-driven responses and may, thus, provide top-down control of the amygdala (Herpetz et al 2001a; Morgan et al 1993; Paradiso et al 1999). In relation to control subjects, the current study on
psychopathy shows increased activation in orbitofrontal and dorsolateral prefrontal regions, right amygdala, and right insula through negative pictures."
