Final answer:
The provided text does not accurately answer the question about Sadao's honesty as the instances are unrelated to the character from Pearl S. Buck's 'The Enemy'. An accurate assessment requires direct references to Sadao's decisions and actions within the story.
Step-by-step explanation:
The question pertains to the character Sadao's actions in a story, presumably 'The Enemy' by Pearl S. Buck, although it is not explicitly mentioned. The instances provided in the question do not relate directly to Sadao or his experiences as they seem to be taken from different texts unrelated to 'The Enemy'. Therefore, it is impossible to accurately assess Sadao's honesty in rescuing the American versus operating on him without the proper context from the literature in question.
However, to generally address such a question within the appropriate context, one would examine the motivations behind Sadao's actions, the risks he undertook, and the consistency of his moral code throughout the events of the story. One would need to compare the tension and stakes for him in both situations before drawing conclusions about the equal degree of honesty displayed.
