There are varying degrees of homicide and one single fact can result in a different charge under homicide laws. Life is defined in the law by statute as is the issue of viability, which can determine whether a statute applies in a given factual situation. For example, for a criminal homicide to occur at common law, the victim had to be born alive. Today, statutes may define life to include a fetus, and some classify illegal abortions as a criminal homicide. At common law, death occurred when the heartbeat and respirations ceased. Now, many courts use the brain death standard, which is said to occur when there is an absence of physiological or electrical brain activity that can be registered. Note that brain death may occur even though respirations and a pulse may continue.
For this discussion, varying charges will be explored. Imagine the following scenario:
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, and she died as a result. The husband was convicted of second-degree murder. On appeal, he argues his actions were taking place during a fit of passion and seeks to have his conviction reduced from second-degree murder to manslaughter.
