INFJ (introverted, intuitive, feeling and judging) personality types are often drawn to "broken" types such as narcissists because they're empaths who take on the pain of others with pure intentions of helping them heal. Introverted personality types are often described as "mediators" or "diplomats".
INFP (introverted, intuitive, feeling and prospecting) usually "give their all" to others which gives narcs an easy "power supply" once the victim is deflated of power, the narc will simply move on to new "supply" of a similar personality type.
The main difference between the 2 is INFJ's tend to be very in touch with their own emotions, whereas INFP types mirror other peoples emotions. Narcs are emotionally intelligent, able to discern exactly how chosen "supply" feels to control their emotions, narcs don't have emotions but simply view feelings as a tool to manipulate/control victims for their own gain. Both types are more susceptible, due to false belief from narcs that "sensitive" personalities succumb easier to bullying from an abuser. This is a living paradox as INFJ's are very compassionate, but will often defend themselves/their loved ones when they perceive their rights are being threatened.
