“Power not only corrupts but also magnifies existing psychopathologies, even as it creates new ones. Fostered by the flattery of underlings and the chants of crowds, a political leader’s grandiosity may morph into grotesque delusions of grandeur. Sociopathic traits may be amplified as the leader discovers that he can violate the norms of civil society and even commit crimes with impunity. And the leader who rules through fear, lies, and betrayal may become increasingly isolated and paranoid, as the loyalty of even his closest confidants must forever be suspect.”
