Esther is now the queen, and she and her Uncle Mordecai saved King Xerxes from an evil plan to kill him. 

The King made Haman a leader of all the King's servants, which was the highest position besides the king. Haman is an evil man, and he hated Jews. He is prideful and loves his new position because it gave him a lot of power. Haman demanded that everyone bow down to him, but Mordecai refused to bow. He says that he can't bow to him because he's a Jew, and he will only worship God. This made Haman mad!

Haman proposed a plan to have the King sign a law that they can kill the Jews. Haman bribed King Xerxes with a lot of money, and he signed the law, not knowing that Queen Esther was a Jew. 

When we look at this part of the story, we can see the plan that Haman made and know it is wrong - it's a sin.
