2 Samuel 13:14

Would not hearken. Amnon was utterly selfish, lustful, and determined to have his own way regardless of consequences. He could not be reasoned with. The requirements of God, the virtue of his sister, and the honor of his own name meant nothing to him. For these characteristics David was in part to blame. He avoided bringing his children to account when they did wrong, and permitted them to have their own way. Now they were beyond reason and restraint.
