Legal Literacy - Criminals of Passion or 'Kejahatan Nafsu' in Indonesian, refers to violent crimes, especially murder, where the perpetrator commits the act against someone due to a sudden strong impulse such as anger or jealousy, rather than as a premeditated crime.

This term is often used in popular culture to describe crimes driven by uncontrolled romantic love, but the reality is often more complex.

Crime in the Perspective of Criminal Law and Criminology

Since ancient times, crime has been a serious phenomenon and problem in people's lives. Some examples of crimes such as persecution, theft, and even murder have existed since ancient times to the current era of modern society.

According to the Kamus Besar Bahasa Indonesia (KBBI) [Great Indonesian Dictionary], crime is human behavior that is contrary to written laws ratified/enforced by the State as well as values and norms that apply in society. Some criminologists essentially define crime as human behavior that is considered to violate norms in society, causing harm and even causing victims. Sociologist Thorsten Sellin even defines crime as a violation of conduct norm (norms of conduct) which sometimes do not have to be contained in law.

Experts criminal law also have their own thoughts regarding the definition of crime which is not much different from the opinions of experts in criminology. Like R. Soesilo defines crime from a juridical point of view as an act of human behavior that is contrary to written law such as the Law, and from a sociological point of view crime is an act of human behavior that harms the victim as the suffering party and often results in the loss of peace in society.

Criminals of Passion

As mentioned earlier, criminology can be used to find out the reasons why someone commits a crime. From a biological perspective, criminology divides or classifies perpetrators of crime into 4 (four) types of groups, namely Born Criminal, Insane Criminal, Occasional Criminal, and Criminals of Passion.

Based on several references in books and scientific journals, the definition of criminals of passion is broadly defined as perpetrators of crimes or criminal acts who commit crimes or criminal acts due to anger or love. This condition ultimately shuts down the reasoning of the perpetrator of the crime and results in the loss of the ability to distinguish between right and wrong.

An example case that can be seen from the perspective of criminals of passion and has attracted considerable public attention is the case of serial murders committed by Very Idham Henyansah alias Ryan Jombang. This case occurred in 2008 and was widely covered by mass media, both print and electronic.

At that time, it was known that the motive for the murder committed by Ryan against his victim was a feeling of jealousy within the framework of a same-sex relationship. The Depok District Court then sentenced Ryan to death in 2009.

Another case occurred in East Jakarta. This murder crime was quite sadistic and involved more than one perpetrator.

A woman with the initials T and a man with the initials BS jointly committed the crime of murder against a female victim with the initials DAS. This criminal event occurred around 2013.

Initially, T and BS collaborated to establish and operate a soto restaurant business located in BS's rented house. Subsequently, T and BS met and became acquainted with the victim DAS, who eventually helped manage and run the soto restaurant business.

Initially, T, BS, and the victim DAS had a good relationship, marked by the three of them taking turns and jointly operating the soto restaurant, keeping it open 24 hours a day. BS, along with T and the victim witness DAS, essentially had a close relationship, and even the relationship was like a married couple.

The problem started when BS suspected the victim DAS of committing adultery. BS often found the victim DAS going out with other men, but the victim DAS refused to reveal the identity of the man. Driven by jealousy, BS then committed violence against the victim DAS, which resulted in the loss of life.

BS, assisted by T, committed a series of violent crimes that resulted in the loss of life of the victim DAS. The act of violence began with continuous beatings using wood to the head and kicking the ribs of the victim DAS.

After ensuring that the victim DAS was no longer breathing, the sadism of T and BS did not stop. The two perpetrators then mutilated the limbs of the victim DAS and put them in a plastic bag. The plastic bag containing the body parts of the victim DAS was then disposed of by T and BS on the Jakarta-Cikampek Toll Road, East Jakarta.

BS was eventually sentenced to 14 years in prison by the East Jakarta District Court. As for T, based on the Decision of the Jakarta High Court Number: 380/PID/2013/PT.DKI dated December 12, 2013, jo. The Decision of the East Jakarta District Court Number: 558/Pid/B/2013/PN.Jkt.Tim dated September 26, 2013, also sentenced her to 14 years in prison because she was proven to have intentionally assisted in committing planned murder.
