To question the jail sentence for the mum who stabbed her 4 year old?

[Liketochat1]

There's such a sad story of a mum who stabbed her 4 year old daughter in the news at the moment.www.telegraph.co.uk/news/uknews/crime/9510938/Nurse-who-stabbed-her-four-year-old-to-death-gets-12-years.html.
She looks like such a broken woman. She not only killed her daughter but also tried to kill herself leaving herself with some brain damage and confined to a wheel chair with other physical disabilities. At the time of the attack she was depressed and facing charges for malpractice and had been left by her partner that day.
She has just been sentenced to 12 years in jail. Do you think she should be jailed? I can't help help but feel she's suffered so much already. Am I unreasonable?

Its a double edged sword- It can be helpful to have it classed under Mental Disorder in terms of detaining someone indefinetly under the MH Act when using it in terms of protection of the public-

Under the old mental health act this wasnt possible- there are now plenty of paedophiles locked away in secure units who are unlikely to ever be released into the general public- previously you couldnt just lock someone up for being a paedophile- now you can if its felt that they are a significant danger to children.
