↑ "In Japanese culture, for example, there are basically two types of suicide: honorable and dishonorable suicide. Honorable suicide is a means of protecting the reputation of one's family after a member has been found guilty of a dishonorable deed such as embezzlement or flunking out of college, or to save the nation as in the case of the kamikaze pilots in World War II. Dishonorable suicide is when one takes his or her life for personal reasons in order to escape some turmoil. This is thought of as a cowardly way out of life and a coward can only bring dishonor to his family." - "The Moral Dimensions of Properly Evaluating and Defining Suicide", by Edward S. Harris, Chowan College
