Matthew Poole and continuators on 2 Samuel 13:15

15 ¶ Then Amnon hated her exceedingly , so that the hatred wherewith he hated her, was greater than the love wherewith he had loved her: and Amnon said unto her, Arise, be gone.

Partly, because his Lust being now satisfied, his mind and conscience had a true and clear prospect, and deep sense of the Natural turpitude and baseness of the action, and of that shame, and contempt, and loss, and mischief, which was likely to follow it, and consequently an utter aversion from her who had been the instrument and occasion of his sin; and principally, by the just Judgment of God both upon Amnon and David, that so the sin might be made publick, and way made for the succeeding Tragedies: for otherwise it would probably produce Love and Kindness to her, as it did in another, Gen. 34. 2, 3. especially in him, whom both Nature, and Interest, and even Lust it self, obliged to allay her grief and shame, by all possible demonstrations of kindness.
