A school shooting is an armed attack at an educational institution, such as a primary school, secondary school, high school or university, involving the use of a firearm. Many school shootings are also categorized as mass shootings due to multiple casualties. The phenomenon is most widespread in the United States, which has the highest number of school-related shootings, although school shootings take place elsewhere in the world. Especially in the United States, school shootings have sparked a political debate over gun violence, zero tolerance policies, gun rights and gun control.
Mass murder is the violent crime of killing a number of people, typically simultaneously or over a relatively short period of time and in close geographic proximity. A mass murder typically occurs in a single location where one or more persons kill several others.
Homicide is an act in which a person causes the death of another person. A homicide requires only a volitional act, or an omission, that causes the death of another, and thus a homicide may result from accidental, reckless, or negligent acts even if there is no intent to cause harm. It is separate from suicide.
Narcissistic personality disorder (NPD) is a personality disorder characterized by a life-long pattern of exaggerated feelings of self-importance, an excessive need for admiration, and a diminished ability to empathize with other people's feelings.

Although definitions vary, most databases require a minimum of four victims for the event to be considered a mass murder.

Sadistic personality disorder was a proposed personality disorder defined by a pervasive pattern of sadistic and cruel behavior. People with this disorder were thought to have desired to control others. It was believed they accomplish this through the use of physical or emotional violence. This diagnosis appeared in an appendix of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III-R). The later versions of the DSM do not include it. It was removed as psychiatrists believed it would be used to legally excuse sadistic behavior.

Since their inception in the 1970s, video games have often been criticized by some for violent content. Politicians, parents, and other activists have claimed that violence in video games can be tied to violent behavior, particularly in children, and have sought ways to regulate the sale of video games. Studies have shown no connection between video games and violent behavior. The American Psychological Association states that while there is a well-established link between violent video games and aggressive behaviors, attributing acts of violence to violent video gaming "is not scientifically sound."
