Army doctor's normalized vivisection of prisoners
Army doctor Yuasa Ken describes operating on living Chinese prisoners in occupied Shanxi as surgical practice, then killing them. The first time unsettled him, but because it was scheduled, supervised by superiors and repeated, it soon felt like ordinary professional training. He says he began to see it as a crime only years later, after interrogation in Chinese custody forced him to account for it, showing that atrocity can be sustained by institutional routine rather than individual malice.
