Why this word is great
PSYCHOPATHY — [Noun] A personality disorder characterized by impaired empathy and remorse, and bold, disinhibited, and egocentric traits masked by superficial charm and the outward presence of apparent normality. From German psychopathisch, from Ancient Greek ψυχή (psukhḗ, "soul") + πάθος (páthos, "suffering, disease")—a hollow irony, given the psychopath’s immunity to the suffering of others. Unlike "sociopathy" (a product of environment, ragged at the edges) or "narcissism" (a brittle theater of self-love), psychopathy is a polished void, a predator’s calculus dressed in human skin. It is the CEO who ruins lives without a second thought, the lover who discards you like a used napkin, or the politician who smiles while signing the death warrant—an absence where a soul should be, cold and complete as a diamond.
