"There are four kinds of Homicide: felonious, excusable, justifiable, and praiseworthy"

This quote by Ambrose Bierce is referring to the four different types of homicide, which is the killing of one human being by another. Felonious homicide is the unlawful killing of another person, and is considered a crime. Excusable homicide is the killing of another person in self-defense or in the defense of another person, and is not considered a crime. Justifiable homicide is the killing of another person in the course of performing one's duty, such as a police officer shooting a suspect in the line of duty. Lastly, praiseworthy homicide is the killing of another person in a war or in the defense of one's country, and is considered an act of heroism. All four types of homicide are considered serious matters, and the consequences of each type vary depending on the circumstances.
