Koro-Sensei
His decision to become a teacher involves his promise to the intern who thought that he was suitable to become one, later revealed to be Class 3-E's former teacher, Aguri Yukimura, who was selected to be his observer during the experiments performed on him and he had fallen in love with. After finding out Yanagisawa intended to dispose of him and he'll die in one year, he went on a rampage slaughtering nearly everyone in the facility except for Aguri and Yanagisawa (whom he blinded in one eye), having decided he didn't care about taking down the world with him. While he was stopped by Aguri, she was mortally wounded by one trap aimed at him, which lead him to become the teacher of class 3-E as it was Aguri's dying wish. According to Koro-sensei, his lifespan will be over by the end of the school year in March, and if he is not killed by then, the whole planet will perish with him due to the explosive release of the anti-matter in his body.
