27. Myra Hindley
Myra Hindley was once branded as the ‘most evil woman in Britain’ – and for good reason. Together with Ian Brady, she was responsible for the ‘Moors murders’ – a spate of horrific murders of 5 young children who were also sexually assaulted.
While Ian was diagnosed a psychopath and was committed to the Ashworth hospital – a high-security institution, Myra was given a life sentence. Though she made several appeals after her sentencing to claim that she has reformed, she was never received of her convictions, and eventually died in 2002 at 60.
