Should chemical castration be introduced for sexual offenders in Malaysia?

While some countries have introduced chemical castration for sexual offenders, simply adopting more extreme punitive measures may offer emotional satisfaction but is unlikely to produce better outcomes, writes criminologist Datuk Dr P. Sundramoorthy.

Should chemical castration be introduced for sexual offenders in Malaysia?

A careful reading of the laws shows that Malaysia adopts a firm, punitive stance towards sexual crimes, particularly those involving children and incest.

Under the Penal Code, rape can carry imprisonment of up to 20 years and whipping, with aggravated cases punishable by 10–30 years or even the death penalty if the victim dies. Incest is treated even more severely, with mandatory imprisonment ranging from 10 to 30 years and whipping. The law also criminalises grooming, exploitation and child sexual abuse materials under the Sexual Offences Against Children Act 2017, reflecting a broader legislative framework aimed at protecting minors.

Against this backdrop, public sentiment in Malaysia, especially on issues such as child sexual abuse and incest, tends to be uncompromising. There is widespread moral condemnation – understandably so, as these crimes violate deeply held social, cultural and religious norms.

However, the key policy question is not whether such crimes are abhorrent – they clearly are – but whether Malaysia should adopt even harsher or more extreme measures, possibly inspired by other jurisdictions.

It should be noted that countries including the United Kingdom, Germany, Sweden, France, Poland, Indonesia and Pakistan employ chemical castration for sex offenders, with approaches ranging from voluntary to mandatory. Methods include hormonal treatment to suppress libido and reduce recidivism.

From a criminological and human rights perspective, any call to implement “chemical castration by giving hormone-blocking drugs” must first be grounded in evidence rather than emotion.

Research consistently shows that the severity of punishment alone is not the most effective deterrent. Malaysia already imposes heavy penalties, including corporal punishment, yet sexual offences continue to occur, including troubling reports involving children in schools and communities.

This suggests that the root causes of sexual offending – such as opportunity, power dynamics, family dysfunction and social silence – cannot be addressed by punishment alone.

Moreover, extreme punitive proposals often raise serious human rights concerns. Malaysia is already scrutinised internationally for practices such as judicial whipping. Expanding punitive measures without safeguards risks violating principles of proportionality, dignity and due process.

More importantly, international human rights standards emphasise not only punishment of offenders but also protection, rehabilitation and justice for victims. A system that focuses excessively on retribution may unintentionally neglect victim support services, trauma care and long-term recovery.

There is also the risk of unintended consequences. Overly harsh penalties can sometimes discourage reporting, especially in incest cases where perpetrators are often family members. Victims may fear the severe consequences imposed on a parent or relative, leading to silence rather than disclosure.

This is particularly relevant in Malaysia, where incest is recognised as a serious but often underreported crime within familial settings. A policy that appears tough on paper may, in practice, reduce cooperation with law enforcement.

A more realistic and effective approach would be to strengthen the certainty of enforcement rather than simply increasing severity. Criminological evidence shows that the likelihood of being caught and prosecuted has a stronger deterrent effect than harsher sentences.

This means investing in specialised investigative units, improving forensic capabilities and ensuring swift judicial processes. Equally important is building trust so that victims – especially children – feel safe to report abuse without fear or stigma.

Prevention must also be central. Comprehensive sexuality education, awareness campaigns and community-based interventions can reduce vulnerability and challenge harmful norms. In schools, stronger safeguarding policies and mandatory reporting mechanisms can play a crucial role.

The Sexual Offences Against Children Act 2017 already recognises grooming and non-physical sexual exploitation, which is a positive step, but enforcement and public awareness remain uneven.

At the same time, offender management should not be ignored. Rehabilitation programmes, psychological assessment and post-release monitoring can reduce recidivism. While this may be unpopular in public discourse, evidence-based corrections policy shows that not all offenders are the same, and a one-size-fits-all punitive approach is neither just nor effective.

It is clear that Malaysia does not lack tough laws on sexual crimes; in fact, it already imposes some of the harshest penalties in the region. The real challenge lies in implementation, prevention, victim support and balancing justice with human rights.

While public anger is understandable, especially in cases involving children, policy must remain grounded in evidence and fairness. Simply adopting more extreme punitive measures, as suggested in viral narratives, may offer emotional satisfaction but is unlikely to produce better outcomes.

A mature society must resist reactionary impulses and instead pursue a holistic strategy that protects victims, deters offenders and upholds the rule of law.
