Hashem is just love, yet we have to hate Amalek. Only when Yerushalayim is destroyed can Esav rise. One of the most significant actions at Har (Mt.) Sinai is that the Jews turned their backs on the other nations. We took away Amalek's view the world and were able to have our own view of the world. Mordechai refused to bow down to Haman, letting him know that his lifestyle means nothing to Mordechai.
