After every gruesome murder, the debate over capital punishment returns.
The issue has resurfaced following last week's alleged murder of five people in Chon Buri by Thana "Pong" Kerdthong, a former inmate who had previously served prison terms for various offences. Another of the four alleged accomplices is also a former inmate.
The debate extends beyond moral arguments over the death penalty. It reflects public anxiety over violent crime and whether the justice system adequately protects society from repeat offenders.
Thailand retains the death penalty but rarely carries it out. The last known execution took place in 2018. If no executions occur before 2028, Thailand will effectively become a de facto abolitionist state.
As of 2024, 364 prisoners were under sentence of death, according to the Thailand Annual Prison Report 2025 by the International Federation for Human Rights and the Union for Civil Liberty.
In practice, many death sentences are commuted to life imprisonment, with the possibility of a royal pardon. Many inmates are eventually released after serving one or two decades. Most successfully rebuild their lives, but some go on to reoffend.
The larger question, however, is not whether Thailand should carry out more executions. It is whether its correctional system is capable of rehabilitating offenders and protecting society from those who remain a danger after their release.
The Department of Corrections is already stretched by the demands of managing overcrowded prisons, leaving limited resources for rehabilitation programmes. Much of its behavioural work relies on religious activities and volunteer programmes. Yet hundreds of thousands of inmates are eventually return to society. According to the Probation Department, about 5,000 former inmates are currently on its watch list.
That raises uncomfortable questions. Does Thailand have an effective system for identifying offenders who remain highly dangerous? If not, does it have a reliable way of monitoring them once they return to society?
Cases such as serial killer Somkid Poompuang, who killed again after being released, inevitably raise doubts about whether post-release monitoring is robust enough.
Lawmakers from the Democrat Party this week floated the idea of legislation to make parole more difficult for repeat offenders. Tightening parole rules may strengthen public safety, but it does not address the deeper problem.
To reduce reoffending, the government must invest far more in rehabilitation, education and vocational training within prisons. These programmes should not be treated as optional acts of charity but as essential investments in public safety.
The Ministry of Justice, police and local authorities must also strengthen information-sharing and supervision of high-risk former inmates.
Ultimately, the best correctional system is one that successfully rehabilitates those who can be reformed while ensuring society is protected from those who cannot.
