These minor, natural flaws did not explain why hers was but the deceptive beauty of the poisoned apple. It was not merely that she was shallow, a creature of simple malice: within her tiny skull a storm raged, hectic, vicious and vengeful. The depths of her character were murky and she herself, had she made the attempt, would struggle to rationalise her behaviour. In morals she was well-versed, for they had been imparted to her through fables as a young child, yet she could find no trace of villainy in her own actions. In her skewed world-view she was set apart.
