This is what the dictionary had to say about the word "sociopath." And right next to the entry they had his picture.

Sociopath: definition. A man who can’t understand others’ feelings. He’ll often break rules or make impulsive decisions without feeling guilty for the harm he causes. He may also use “mind games” to control friends, family members, co-workers, and even strangers. He may also be perceived as charismatic or charming.
