An entire generation can sometimes abandon the right path, leaving behind a bleak reality where wickedness dominates and holiness finds no place [ביאור שטיינזלץ]. The primary approach among commentators is that society undergoes a severe regression, stepping back and turning away from the path of good [מצודת ציון, מצודת דוד, מאירי, ביאור שטיינזלץ]. This is not a sudden shift, but rather an ongoing, continuous backward movement [מאירי]. Looking at it from another angle, this regression transforms the people into something akin to dross or impure waste [רש״י].
As they pull away from goodness, a deep moral corruption takes hold. The people become spoiled, foul, and entirely stained by their poor character [מצודת ציון, מצודת דוד, ביאור שטיינזלץ]. They are covered in a spiritual filth that completely ruins their moral standing [מאירי]. The result is an absolute absence of good, creating an environment where wicked individuals are everywhere, constantly harming those who try to live properly [ביאור שטיינזלץ]. In a ruling or military setting, this means that out of an entire army or government force, there is not a single person willing to stand up and protest the actions of the wicked [רש״י].
This widespread state of decay and helplessness can also be viewed through the events of the Purim story. In this context, the idea of stepping back hints at the political attempt to retreat from and cancel Haman's death decree by sending out a second set of royal letters. The corruption and hopelessness describe the seemingly unfixable nature of the crisis, as the king's original decree could not be completely erased. During this terrifying time, the complete lack of anyone doing good actually reflects the spiritual state of the Israelites. Even after seeing Mordecai crying out in the streets, the people had not yet fully returned to God in complete repentance. It was only later, through Esther's direct intervention, that the situation began to change [אלשיך].
