He might be sadistic and cruel. And maybe he's apathetic and selfish. Also, he is Hypocritical and Pathetic. All those things I totally agree with. but you must remember, he is also Comedic and Entertaining. He is Unflappable and Calm. Not to mention Highly Observant. Also, his past is kinda messed up.
He has Deep-Seated Grief and Loneliness. He has Vulnerability and Fear. He also has Traumatized Defensiveness. Lets agree on that. Anyways, that's why I love him.
