The depth of ingratitude[1]
…וישלח ויבא את-אהביו ואת-זרש אשתו: ויספר להם המן את-כבוד עשרו ורב בניו ואת כל-אשר גדלו המלך ואת אשר נשאו על-השרים ועבדי המלך: ויאמר המן וגו’ וכל-זה איננו שוה לי בכל-עת אשר אני ארה את-מרדכי היהודי יושב בשער המלך
…[Haman] sent for and brought his friends and his wife Zeresh. He spoke to them about all of his glory, wealth, multitude of children, the promotions that the King had given him, how he was in charge of all the ministers and slaves of the King. Haman said [to them]: “…All of this is worthless to me, so long as I see Mordechai the Jew sitting in the gate of the King”[2]
Towards the end of the Megillah, Haman practically had a mental breakdown. His arch nemesis Mordechai was still alive, despite Haman’s desire that all the Jews be killed. Haman himself delayed Mordechai’s execution, in order to kill his entire people on the same day. It’s clear that Haman had grown impatient, waiting for the decreed day’s arrival. He complained to his family and friends that he felt like nothing in his life mattered, so long as Mordechai the Jew was alive.
