Yet Mordecai's good behavior is useless if the king doesn't know about it. Suppose mass media existed and hadn't covered Mordecai's behavior but reported on all of Haman's speeches?
What if Esther was not such a good person, or didn't have Mordecai to advise her? What if she knew that she would not be punished but in fact could benefit from remaining silent or even joining into the denunciation of the Jews of the day? Suppose she could have redefined the situation to say that there were in fact good, pro-Persian Empire Jews as opposed to those bad Jews who wanted to return from exile in the Persian Empire to the Land of Israel, from which her great-great-grandfather had been taken as prisoner?
