During a domestic quarrel a wife continually taunted her husband by degrading him and telling him he was a "lousy lover" and that she wanted to be rid of him. When the husband tried to persuade her to relent she continued to taunt him in a louder voice. Finally, he grabbed a kitchen knife and stabbed her. As a result she died. The husband was convicted of second-degree murder. On appeal he argues his actions were taken during a "fit of passion" and seeks to have his conviction reduced from second-degree murder to manslaughter. Is he likely to succeed? Why or why not?
