Jamie: “If there are gods, why is the world so full of pain and injustice?”
Catelyn: “Because of men like you.”
Jamie: “There are no men like me; only me.”
At first glance, outsiders perceive Jaime to be arrogant, cocky, cold, dishonorable, extremely dangerous, disdainful, and sarcastic. To a large extent he is arrogant about his own abilities, but not without cause. Jaime was arguably one of the greatest swordsmen ever, but the loss of his sword-hand warped his abilities, which did much to humble him.
Jaime does not mock others over minor insults the way Cersei does, and he can muster up polite behavior, but he is usually very blunt and straightforward. Much like his brother Tyrion, he typically just says what he is thinking, and has no reservations about mocking those he perceives as incompetent. Underneath this cold and sarcastic attitude, Jaime is a very complicated man.
