Divine justice often operates as a direct reflection of human choices, creating a perfect mirror between a person's actions and their ultimate fate. The punishment falling upon the people operates strictly on the principle of measure for measure, directly reflecting their own behavior and attitudes.
God's refusal to show pity or offer compassion is understood by the primary approach among commentators through a moral and social lens. The people had acted with cruelty, refusing to show mercy to one another or to the poor among them. In direct response to their ruthless behavior, God mirrors their actions and withholds His own mercy [מלבי״ם, רד״ק, ביאור שטיינזלץ].
Beyond their social failures, this lack of divine compassion is also tied to their deeply flawed beliefs. The people had falsely convinced themselves that God does not see their actions. Consequently, God responds in kind, determining that His eye will essentially look away, refusing to see them in a way that would awaken pity [מצודת דוד].
Ultimately, this principle of exact retribution ensures that the people bear the full weight of their choices. God returns their deeds directly upon their own heads. The punishment they experience is not arbitrary; it is the exact reality they created, brought down upon them in the precise way they chose to sin [מצודת דוד, ביאור שטיינזלץ].
