32 But Jonadab, the son of David's brother Shimeah, said, "Let not my lord suppose that they have killed all the young men the king's sons; Amnon alone is dead. This has been determined by Absalom from the day Amnon raped his sister Tamar.

Matthew Henry's Commentary on 2 Samuel 13:32

Commentary on 2 Samuel 13:30-39

(Read 2 Samuel 13:30-39)

Jonadab was as guilty of Ammon's death, as of his sin; such false friends do they prove, who counsel us to do wickedly. Instead of loathing Absalom as a murderer, David, after a time, longed to go forth to him. This was David's infirmity: God saw something in his heart that made a difference, else we should have thought that he, as much as Eli, honoured his sons more than God.
