Seriously, if you want to study a good sociopathic character, Dennis from It’s Always Sunny in Philadelphia is perfect. Though it’s a comedy series, it is the most accurate depiction of a narcissistic sociopath I’ve ever seen. He seems very normal, charming even, but he cannot feel love, and only does anything (even helping his “friends”) for his own benifit. Brilliantly acted. I know you’re probably twisting your nose up right now, but trust me. He does something very, very dark with that character that is only revealed every once in a while. He’s not lurking in the shadows or autistic or strange, he’s a seemingly normal person with some very serious issues and an extremely shallow point of view. The more you watch the show, the more you realize that he cannot feel deeply. Ever. It’s fascinating, really.
