More than two years after the death of the one-year-old boy known as Kai Kai (剴剴), who succumbed to injuries inflicted through sustained abuse by his caregivers, the nation is still grappling with how to seek accountability and reform the system that failed to protect him.
The Taipei District Court on Thursday last week sentenced Chen Shang-chieh (陳尚潔), a social worker with the Child Welfare League Foundation (CWLF), to two years in prison for negligent homicide. Chen was responsible for overseeing Kai Kai’s case, placing him in the care of two licensed nannies, sisters Liu Tsai-hsuan (劉彩萱) and Liu Juo-lin (劉若琳), who were later convicted of torturing him to death and sentenced to life imprisonment and 18 years respectively.
The court found that, during her three visits to Kai Kai, Chen overlooked multiple warning signs, such as recurring illness and visible injuries. Rather than insisting Kai Kai receive medical treatment or increasing the frequency of her visits, Chen proceeded as usual, even allowing scheduled check-ins to be postponed at Liu Tsai-hsuan’s request. The court concluded that Chen’s “passive inactivity” directly contributed to Kai Kai’s death.
The public’s reaction to the ruling has been sharply divided.
Some said that the sentence is too lenient, arguing that Chen, as the professional responsible for the case, failed in a duty that carried life-and-death consequences. Meanwhile, dozens of social worker associations and civic groups protested outside the Executive Yuan on Tuesday, asserting that Chen is being used as a scapegoat for a tragedy caused by a flawed system.
Both sides of the debate raise valid points. As the social worker who assigned the Liu sisters as Kai Kai’s caregivers, Chen held a critical position and — by the court’s own assessment — missed multiple opportunities to intervene. Had she exercised greater vigilance, Kai Kai might still be alive today.
At the same time, placing the blame on Chen overlooks the underlying issues that made this possible. The Liu sisters were not operating outside the system — they were licensed and had no known prior misconduct. The fact that someone like Liu Tsai-hsuan, who was found to derive pleasure from abusing an infant, was approved as a licensed caregiver raises serious questions about the integrity of screening mechanisms.
Kai Kai’s tragic passing was not the result of a single lapse, but of a flawed and fragmented institutional structure in which responsibility is unevenly dispersed and accountability is often unclear.
This does not absolve Chen of responsibility, but it does challenge the notion that the incident begins and ends with her. The primary culpability lies, unquestionably, with those who abused Kai Kai. However, the system must also be scrutinized as a major contributing factor — not merely as a backdrop.
To prevent cases like Chen’s, guidelines for intervention on the part of social workers should be made clearer and more enforceable — for example, standardizing follow-ups when children show unexplained injuries or illness, normalizing surprise visits and setting out clearer escalation steps in high-risk cases. However, without enough staff even well-designed regulations would prove ineffective.
Frontline social workers cannot be expected to carry a level of responsibility the system itself cannot realistically support.
The social work sector is already stretched thin, characterized by heavy caseloads, limited personnel and relatively low pay. Neglecting to address these structural constraints after such a high-profile case might drive more workers out of the field, further weakening the very system meant to protect vulnerable children.
That being said, reforms cannot be limited to one part of the system. Screening, training and certification standards for childcare providers must be made more comprehensive to make sure there is absolutely no opportunity for child abusers to work in the field.
Encouragingly, the Ministry of Health and Welfare this week announced amendments to the Child and Juvenile Welfare and Rights Protection Act (兒童及少年福利與權益保障法) that would establish a permit system for professions involving contact with children and more clearly define institutional responsibilities and misconduct in childcare. However, that is only the beginning of what needs to be done. Institutional reform must be constant, coordinated and based on a realistic understanding of how childcare and protection work in practice.
Kai Kai’s case is a tragedy that should never have occurred. However, now that the courts have delivered their rulings, further debate over how blame should be apportioned risks distracting from what matters most — addressing the systemic failures that put him in danger.
