Counting the Omer is not just a mitzvah, but is a mitzvah based in Kabbalah. We are instructed to count the Omer, but what are we counting? Why count 49 days of the Omer at all?
In Season 5 of the CW show, Arrow, the (spoilers) Green Arrow is captured and forced to recognize his own sins. He comes to the realization that he has enjoyed killing people and disguised it as a righteous crusade. Halacha of television and murder aside, there is the recognition by Oliver that he had the right mission, but a wrong desire in that mission, leading him to sin. In the process of his repentance, however, he condemned himself as a monster and determined to push others away. Only at the persistence of his team did he return to the fold and realize that he needed to reconsider his motives before he continued in the field of vigilantism. This brings up excellent questions regarding morality, sin, and repentance with the High Holidays around the corner.
