Brazen
Another attribute that is needed for our battle is brazenness, as it states (Avos 5:20), הוי שבשמים אביך רצון לעשות ...כנמר עז, "Be brazen like a leopard...to do the will of your Father in heaven." Shulchan Aruch (1:1) says that this means doing what you should and without being embarrassed or concerned about what others say.
This is also needed in a war between countries. Imagine a government constantly asking itself, "What will other countries say if I do this and this?" The leaders of a war need to know what is correct and to carry it out brazenly. The same applies to our fight against the yetzer hara. If we only do what others expect from us, we will refrain from doing many good deeds. But when we have the attribute of holy עזות, brazenness, we can succeed in our war against the yetzer hara.
Once, the Kedushas Yom Tov attended a rabbinic meeting with his son, Reb Yoel (who later became the Satmar Rebbe zt'l). Reb Yoel davened with hand gestures, which helped him have kavanah. One of the rabbanim thought it was funny and asked Reb Yoel, "Is it Purim today?" The young Reb Yoel replied, "If I knew I would be meeting Haman, I would bring along my grager."
Haman and Amalek make fun of yiras shamayim. As it states, בדרך קרך אשר, "Who cooled you off when you were traveling on the way." We must serve Hashem with confidence and audacity. We shouldn’t be afraid to serve Hashem with fervor.
As is stated at the beginning of Shulchan Aruch, יתברך 'ה בעבודת עליו המלעיגים אדם בני מפני יתבייש ולא, "Don't be afraid when people make fun of you serving Hashem."
