There are four different subtypes of psychopaths:

DISTEMPERED PSYCHOPATHS are the kind that seem to fly into a rage or frenzy more easily and more often than other subtypes. Their frenzy will resemble an epileptic fit. They are also usually men with incredibly strong sex drives, capable of astonishing feats of sexual energy, and seemingly obsessed by sexual urges during a large part of their waking lives. Powerful cravings also seem to characterize them, as in drug addiction, kleptomania, pedophilia, any illicit or illegal indulgence. They like the endorphin "high" or "rush" off of excitement and risk-taking. The serial-rapist-murderer known as the Boston Strangler was such a psychopath.

CHARISMATIC PSYCHOPATHS are charming, attractive liars. They are usually gifted at some talent or another, and they use it to their advantage in manipulating others. They are usually fast-talkers, and possess an almost demonic ability to persuade others out of everything they own, even their lives. Leaders of religious sects or cults, for example, might be psychopaths if they lead their followers to their deaths. This subtype often comes to believe in their own fictions. They are irresistible.

PRIMARY PSYCHOPATHS do not respond to punishment, apprehension, stress, or disapproval. They seem to be able to inhibit their antisocial impulses most of the time, not because of conscience, but because it suits their purpose at the time. Words do not seem to have the same meaning for them as they do for us. In fact, it's unclear if they even grasp the meaning of their own words, a condition that Cleckley called "semantic aphasia." They don't follow any life plan, and it seems as if they are incapable of experiencing any genuine emotion.

SECONDARY PSYCHOPATHS are risk-takers, but are also more likely to be stress-reactive, worriers, and guilt-prone. They expose themselves to more stress than the average person, but they are as vulnerable to stress as the average person. They are daring, adventurous, unconventional people who began playing by their own rules early in life. They are strongly driven by a desire to escape or avoid pain, but are unable to resist temptation. As their anxiety increases toward some forbidden object, so does their attraction to it. They live their lives by the lure of temptation.
