Why did Mdisho kill Fritz Kleiber?

The correct reason for why Mdisho killed Fritz Kleiber is related to the context of loyalty and identity during a time of conflict. Mdisho's actions are not solely driven by Kleiber's nationality as a German, but rather by a broader sense of wartime dynamics and personal loyalty. The situation reveals a deep-seated animosity rooted in the complexities of colonial and wartime relationships, where allegiance and betrayal were intensely scrutinized.

Choosing this particular option reflects an understanding of the antagonism during the historical context in which the narrative unfolds. It suggests that Kleiber's identification as German represented a significant dividing line in loyalties, highlighting how national identity can lead to fatal consequences in a war-torn environment. It's essential to recognize how the historical context influences personal actions, making this the most relevant reason for the conflict leading to Kleiber's death.
