Purim

Why did Mordechai have to incite Haman by not bowing down to him? Why couldn't he just arrange to lose his job of sitting at the palace gates or retire from it or move away or pretend to be sick or something? He can't make a point of not bowing down and thereby jepordize his life and the lives of his fellow Jews! Also the Gemara (Megilla 6b) says "I'm Ra'isah Rasha Shehasha'ah Misachekes lo al tisgareh bo" ( it's assur to incite a rasha that is enjoying good fortune), so how could he have incited Haman? Haman was clearly enjoying good fortune!
