The Kozhnitzer Maggid further expands on this concept and provides us with an even deeper insight into the nature of the yetzer hora. He explains that actually the yetzer hora himself is not interested in people falling into his trap, quite the contrary. As a divine being, a Malach, the Yetzer Hora's only desire is to fulfill Hashem's will. He performs his duty faithfully, but he is there so that people can overcome him, not chas vesholom stumble due to him.
Therefore, when the Malach wrestled with Yaakov Avinu and was overcome, he asked for permission to go and sing his שִׁירָה, claiming that his long-awaited turn to sing for Hashem had arrived. The Kozhnitzer Maggid explains that a Malach sings when his purpose has been fulfilled, and this is exactly what happened when Yaakov triumphed over the Malach of Eisav. By providing Yaakov the opportunity to fight him, and triumph over him, the yetzer hora had fulfilled his purpose and therefore his time has come to sing Shirah to Hashem.
(עֲב׆דַת יִשְׂרָאל יִשְׁלַח ד"ה וְשָׁמַעְתִי)
May we indeed merit, to view the yetzer hora, with the right perspective. For its purpose is not to cause us to sin, but rather to provide us with opportunities to overcome it and grow spiritually as a result. It is only through resistance and overcoming the challenges it presents us with that we can truly reach our full potential and fulfill Hashem's will for us. By remembering that the yetzer hora is nothing but a tool provided to us so that we can fight it and thus achieve greatness, we can indeed hasten the day when the Yetzer Hora will finally be slaughtered, may it be speedily in our days. אמן
