In Megillat Esther, 3:15, after the king sends out his edict, the text says וְהָעִ֥יר שׁוּשָׁ֖ן נָבֽוֹכָה, and the city of Shushan was confounded (or perturbed).
Clearly, the Jews were, but the non-Jews who, according to the Medrash, approached Jews and said "tomorrow I will kill you" did not seem perturbed. The only explanation I have seen is that the proclamation's contents were actually unknown in the city (having only been proclaimed in the "fortress" so everyone was confused. But if that is the case, then the non-Jews would have no reason to accost the Jews. Is there any explanation for why the non-Jews would be considered "n'vuchim"?
While I have a theory, I would like to know if any of the commentators can explain the "perturbed-ness" of the non-Jews.
