This document outlines the topics that will be covered in Module 4 of an online course about why people kill. Over the course of 5 days, the module will explore the biological and social factors that influence different types of homicide: - Day 1 discusses the difference between killing and murder and how societies determine what deaths are lawful or unlawful. - Day 2 focuses on domestic homicides, particularly factors that increase the risk of a child being killed, such as having a stepfather or a young, single mother. - Day 3 examines crimes of passion and how escalating aggression in men can lead to killing spouses or other men, influenced by testosterone levels. - Day 4 analyzes serial killers, their

Module 4: Why People Kill
Module 4: Day 1 What is murder? A thief steal property but a killer steals lives. Perhaps that why every society has stiff penalties for unlawful killing. But what makes some deaths unlawful while others are tolerated or even sanctioned by society? Today, we explore the way that people value lives based on relatedness, age, and relationship. You will learn that the difference between killing and murder has everything to do with evolutionary biology.
Module 4: Day 2 Domestic Homicides Most murders are committed by men, and many of these murders occur inside the home. Today, we explore the factors that cause people to kill their children. You will learn that having a stepfather or a mother who is poor, young, and single puts a child at greater risk of homicide.
Module 4: Day 3 Crimes of Passion Many homicides occur when men react violently to a stressful situation. Today, we explore how escalating aggression causes men to kill their spouses and other men. You will learn that testosterone puts a man at risk of escalating aggression with other men. Similarly, women are most at risk of being killed at an age when their husbands have high levels of testosterone.
Module 4: Day 4 Cold-blooded Killers Hollywood periodically stokes our fascination with serial killers, but these people are fortunately rare in society. Nevertheless, we should consider what makes them so rare as much as we should wonder what makes them behave so abnormally. Today, we explore the habits, motivations, and neurobiology of serial killers. You will learn that male and female serial killers differ in frequency, behavior, and motivation. But both kinds of serial killers have psychopathic traits that stem from altered function of the brain.
Module 4: Day 5 Organized Murder Organized crime gets a bad rap when you consider that nations can steal and kill honorably by just declaring war. This mass- killing between groups has been sanctioned by every society at one time or another. Today, we explore the frequency of war among humans and other primates. You will learn that humans are more violent that their relatives, have spread their genes and culture through war, and may be genetically programmed for prejudice against outgroups.
