Adds layers to the moral dilemma -- the historical context of World War II - hostilities between Japan and the United States – their choice forces the characters to confront their ingrained prejudices and challenge societal norms.
The wounded soldier's identity as an American POW -- questions the dehumanisation of the enemy during wartime, emphasising shared vulnerabilities and the common thread of suffering - the moral dilemma becomes not just about allegiance to one's nation but also about recognising the shared humanity that transcends national conflicts.
