2 Samuel 18:33

And the king, weakly losing sight of the avenging hand of God in this death, was much moved, and went up to the chamber over the gate, probably that used by the watchmen of the city, and wept, and as he went, thus he said, O my son Absalom, my son, my son Absalom! Would God I had died for thee, O Absalom, my son, my son! He was more deeply afflicted by the death of this rebellious son than by any event in his life. It is a blessing of God if dangerous and rebellious people, who lead others into temptation and destruction, are destroyed by God's wrath. In such cases the believers have all reason to thank and praise God for the justice of His punishments.
