But history has shown that sometimes the people we trust the most can be the most dangerous of all. Behind their uniforms, rosaries, or gentle smiles, these caregivers committed unthinkable acts.
Netflix documentaries and true crime shows often spotlight notorious serial killers, but rarely do they shine a light on the nurses, nuns, and caretakers who turned places of safety into chambers of horror. These are not just stories of murder—they are betrayals of faith, family, and trust.

Her case shocked a nation where nuns were seen as holy protectors. When she was finally exposed, the betrayal rocked Belgium’s faith in religious caregivers.
