The term "mass murder" refers to the act of killing a large number of people, typically in a single event or incident. It is not defined by the motive behind the killings, but rather by the sheer scale and magnitude of loss of life involved. Mass murders can be carried out using various methods such as shooting, stabbing, bludgeoning, poisoning, or even through explosives. The perpetrator may target a specific group of people based on their race, religion, nationality, occupation, or other factors, or the victims may be chosen at random. Mass murder is considered one of the most heinous crimes and is often committed with the intention to terrorize society or to draw attention to a particular cause.
