She was forced to play the Persona Nonary Game so that her crimes can be exposed. The reason why she kills is because she never knew her own family and was jealous. When it was revealed that her family was playing the Persona Nonary Game and that her mother died giving birth to her last child, she went from cold blooded to broken hearted because of what she had done.
