Everyone has a little darkness in them. The Short Dark Tetrad (SD4), a 28-statement questionnaire by personality psychologist Delroy Paulhus and colleagues, looks at four everyday 'dark' traits: Crafty (Machiavellianism), Special (narcissism), Wild (psychopathy) and Mean (sadism). It takes about seven minutes and shows which side shows most in your answers. It is a personality questionnaire, not a diagnosis.
