By the time the story takes place, Obito has become cruel, ruthless, scornful and deeply selfish. He has a calm, patient and dead-serious attitude, being most often polite and easy-going but displaying scathing contempt at times. He hates being betrayed and will track down anyone who failed to honor a bargain or defected. He also is shown to be quite sadistic. Even if he will be patient with you, he is willing to make you join him with his goal as he sees you a useful person.
