In the summer of 1941, Adolf Hitler made the controversial decision to halt the T4 euthanasia program, which aimed at eliminating individuals deemed 'life unworthy of life,' such as the mentally ill and physically handicapped. This decision was heavily influenced by growing protests from the public and religious communities, particularly following an open letter by a group of German bishops that condemned the killings. The backlash reflected a significant moral outcry and raised questions about the ethics of the Nazi regime's eugenics policies. Nevertheless, despite the official cessation order, the systematic killings did not completely stop; instead, they became more covert. Operating in secrecy, medical professionals and SS officers continued to murder thousands through starvation, lethal injections, and deportations to concentration camps. The schism within the Nazi leadership regarding the ethical implications of the euthanasia program revealed internal struggles over how to manage their genocidal policies while maintaining public order and appeasing dissenters. This marked a pivotal moment in the escalation of Nazi terror, demonstrating both the regime's capacity for ruthless control and the fragility of its ideological frameworks.
