Haman tried hard to avoid the humiliation of leading Mordecai through the streets of Shushan; he implored the king to spare him that disgrace and offered every kind of reparation to Mordecai, but the king remained inflexible (Targum Sheni vi.) [REF].
It is also said that when King Ahasuerus rose from the banquet in anger and went into his garden he saw angels in the form of men felling the trees, who said that they were ordered to do so by Haman (ib.) [REF].
