Psychopathy is typically viewed as a mental disorder characterized by abnormal or violent behavior without conscience or empathy. Psychopaths manipulate others through lies and deception to get what they want. Key traits include lack of remorse, need for stimulation, pathological lying, parasitic lifestyle, promiscuity, and failure to accept responsibility. While some are violent criminals, others are more subtle. Famous movie psychopaths portrayed in an entertaining way include Norman Bates, Alex DeLarge, and Dexter Morgan, though movies do not always accurately represent gender balance in psychopathy.
