6. Only rarely in difficulty with the law, but seeks out situations where their tyrannical behavior will be tolerated, condoned, or admired
7. Conventional appearance
8. Goal of enslavement of their victim(s)
9. Exercises despotic control over every aspect of the victim’s life
10. Has an emotional need to justify their crimes and therefore needs their victim’s affirmation (respect, gratitude and love)

14. Extreme narcissism and grandiose
