Summary
Analysis
John witnesses the last rites, administered by Dr. Koenigswald—who is not completely sure how they go. Even though he’s a scientist, he says “I will do anything to make a human being feel better, even if it’s unscientific.” Dr. Koenigswald gets into position to perform boko-maru with “Papa”.
Here, Koenigswald expresses a relatively noble sentiment towards alleviating the suffering of others. The only problem is, he used to be a Nazi physician. Just like every other moment in the novel in which there seems to be a move towards a moral position, it’s undercut by the absurdism of the situation.
