Amon's reign stands as a dark period defined by a stubborn refusal to change course. Unlike his father Manasseh, who eventually humbled himself before God and sought forgiveness, Amon chose a path of constant rebellion. His actions were not merely missteps but severe crimes and deep iniquity [מצודת ציון].
There was a striking consistency to his wickedness. From the very beginning of his rule until his final days, he remained entirely fixed in his evil ways, never once turning back or showing remorse [מצודת דוד]. What makes his legacy particularly notable is the sheer volume of his wrongdoing in such a short time. Although he did not live a long life, he managed to multiply his guilt immensely. Ultimately, his sins were even more harsh and severe than the transgressions of his father [ביאור שטיינזלץ].
