Terrorists are people who commit unforgivable atrocities for political or religious gain or other demands. Many terrorists believe what they are doing is right but have no qualms about killing innocent civilians in order to achieve their goals: in fact unlike most soldiers, terrorists often deliberately target civilians as they see "terror" as a valuable tool of getting what they desire.

Terrorists can also be linked to other crimes such as piracy, drug-dealing and slavery - which they may do to fund their cause or as a means to gain more notoriety for themselves.
