Understanding these motivations helps law enforcement and psychologists develop different strategies for prevention and rehabilitation, as instrumental offenders may be more easily deterred by "increasing the cost" of the crime (e.g., better security or harsher penalties).
Committing murder for a fee rather than personal animosity.
Engaging in illegal trade strictly for profit.
The crime is a means to an end . It is a way to solve a problem or acquire a resource.
The crime is the goal. It serves to vent frustration, rage, or jealousy (e.g., a bar fight).
The primary focus is the end result (e.g., stealing money, gaining power) rather than the act of violence itself.
The offender typically weighs the risks against the potential rewards.
