Sforno on Deuteronomy 24:16/ספורנו על דברים כ״ד:ט״ז

1לא יומתו אבות על בנים, even if the crime involved was insurrection against the established authority, king, etc. It had been a widely accepted rule that kings would also execute the family members of rebels in order to ensure that the surviving relatives of such executed rebels would not form an active opposition to the king as a result of their grievance. Such matters are referred to in Isaiah 14,21 “prepare a slaughtering block for his sons because of the guilt of their father. Let them not arise to possess the earth! Then the world’s face shall be covered with towns.” The meaning of the word שונאים which I used earlier is to be understood as in Samuel I 28,16 ויהי ערך, “he became a foe.” In any event, the Torah prohibits Jewish kings from killing one person as a substitute for another; this is part of G’d’s pity for members of His people. Amatziah, King of Yehudah, abided by this legislation when he executed the servants who had killed his father but did not touch their children (Chronicles II 25, 3-4)
