Those who claimed that giving herself over to the Darkness that had been inside of her from birth was somehow out of her character were fools who knew nothing. She hadn't been blameless when she was a child either. Marietta Edgecombe would carry the scars of her curse until the day that she died. Dolores Umbridge would never be able to enter a forest without dissolving into panic, never be able to see a centaur without remembering the scars she carried from that day a teenage Hermione led her into the Forbidden Forest. Neither of those acts had been done without conscious thought on her part. She knew what she was doing. She knew trapping a woman in an unbreakable jar wasn't a so-called normal act that a rational person would commit. It was calculated and designed to make the most impact.
