Four types of mass murderers:
- Revenge killers seek to get even with individuals or society at large. Their target is an estranged wife and “her” children or an employer and “his” employees.
- Love killers are motivated by a warped sense of devotion. They are often despondent people who commit suicide and take others, such as a wife and children, with them.
- Profit killers are usually trying to cover up a crime, eliminate witnesses, and carry out a criminal conspiracy.
- Terrotist killers are trying to send a message. Gang killings tell rivals to watch out; cult killers may actually leave a message behind to warm society about impending doom.
