LettersHong Kong DSE history exam: Japanese invasion of China is no subject for a cost-benefit analysis
- The carnage wrought on Chinese soil, including in Hong Kong, during the Japanese occupation should not be so easily dismissed
- Asking if more good than harm came out a period including the Japanese invasion risks normalising war crimes

The Japanese invasion, and subsequent occupation of Hong Kong for three years and eight months, wrought tremendous carnage and devastation in China. Even if some people hate to identify themselves as Chinese, how could anyone who truly loves Hong Kong rub salt into the wound?
What the Japanese invasion meant to the Chinese people is tantamount to what Nazism meant for the West. It is unimaginable that a similarly provocative question about Nazism could possibly appear in a Western public exam paper.
Some people argue that students could rebut the exam question. But not everything is suitable for a cost-benefit analysis. By forcing students to compare the “good” and “harm” of a period including the Japanese invasion, the HKEAA effectively insinuates that war crimes might be tolerable, provided that the war criminals had done enough “good” to offset the “harm”.

Following this logic, our condemnation of war crimes would become less natural and unconditional, and more calculative, taking into account the “good” done by war criminals. To borrow Michael Sandel’s words, in his analysis of the impact of market values, such logic leaves “their mark on social norms”; whatever conclusions one may reach in the end, the mere act of comparison already “corrupts” our moral norms and “taints” our respect for human life and dignity.
