The end of vile man

Esther 7:7-10
"Will he even molest(騷擾,調戲) the queen while she is with me in the house?"
They handed Haman on the gallows he had prepared for Mordecai, Then the king's fury subsided.
And his action in throwing himself as Esther's feet as she reclines on her couch only succeeds in adding attempted rape to the charges against him(強加了對他的指控).
In the supreme irony of things, he ends his life on the gallows he himself had made.
Why?
It is not know why king had so interpretation to Haman's action, may be under the fury king saw Haman's behavior was against queen and king.
Be a humble and righteous man before the Lord. What can I do?
How?
Humble myself everyday and examine myself before the Lord, obey the commands of God!
