Matthew Henry on 2 Chronicles 33:21-25

Amon's father did ill, but he did worse. Whatever warnings or convictions he had, he never humbled himself. He was soon cut off in his sins, and made a warning for all men not to abuse the example of God's patience and mercy to Manasseh, as an encouragement to continue in sin. May God help us to be honest to ourselves, and to think aright respecting our own character, before death fixes us in an unchangeable state.
