Because humans are complicated beasts, the monster said. How can a queen be both a good witch and a bad witch? How can a prince be a murderer and a saviour?

The answer is that it does not matter what you think, the monster said, because your mind will contradict itself a hundred times each day. You wanted her to go at the same time you were desperate for me to save her. Your mind will believe comforting lies while also knowing the painful truths that make those lies necessary. And your mind will punish you for believing both.
