The collapse of evil is characterized not merely by total loss, but by suddenness and profound humiliation. The primary approach among commentators is that the destruction of the wicked is compared to human waste [רש״י, מצודת ציון, רלב״ג, אבן עזרא, ביאור שטיינזלץ]. A wicked person will perish quickly and permanently, much like dung that is discarded and completely burned away, leaving no memory behind [מצודת דוד, אבן עזרא]. His success and high status are ultimately nothing more than a tower of waste, inevitably doomed to crumble into nothingness [ביאור שטיינזלץ]. On a deeper level, his behavior is compared to a person who dirties a king's palace with his sin, resulting in his immediate removal and destruction [אלשיך].
Alternatively, this sudden ruin is understood through the concept of a rapid fall or tumble [מלבי״ם, רמב״ן]. The moment a wicked person slips and deviates even slightly from his lofty position, he instantly plummets. Like a man falling from a high roof into a deep pit, he is lost forever, completely unable to halt his rapid descent [מלבי״ם, רמב״ן].
The aftermath of this downfall leaves the surrounding society in absolute shock. Because the collapse is not gradual but entirely sudden, those who saw the wicked person at the peak of his success just a moment prior will search for him in disbelief. They will wonder where he is and how he vanished so completely, as no trace of him remains [מצודת דוד, מלבי״ם, ביאור שטיינזלץ].
From a different perspective, the onlookers' confusion does not stem from a physical disappearance, but from a fundamental change in the person's nature. His glow, posture, and overall character are so severely altered by his sin and downfall that observers simply do not recognize him as the same individual. This profound shift is compared to God calling out to Adam after his sin to ask where he was, a question that highlighted the tragic loss of his former standing [אלשיך].
