A lighter sentence? Are you serious? Even though she is sick, you can't let her out. She s a danger to society, so you have to keep her locked away, whether it's a prison or a place for dangerous schizophrenia patients. How much hate and criminal energy do you need to have to stab someone 200 times? Its definitely not human. Especially the person that gave birth to you, she should be happy that she didn't get death sentence. In another state or country it might have been.
