A request by Beverley Allitt, the nurse who murdered four children, to have her sentences reviewed has been condemned by a former colleague.
Allitt is serving 13 life sentences at Rampton in Nottinghamshire
Allitt is serving 13 life sentences for the murders and attacks on nine other children at a Lincolnshire Hospital.
The victims' families have been consulted about a possible reduction in her 40-year minimum tariff.
Jean Burgess, who worked at Grantham Hospital at the same time as Allitt, said she was "dismayed" at the news.
Allitt, dubbed the "Angel of Death", was given 13 life sentences at Nottingham Crown Court in 1993 for the crimes she committed while working at the Grantham and Kesteven Hospital, in Grantham.
She was detained at Rampton High Security Hospital, Nottinghamshire, after being diagnosed as suffering from Munchausen Syndrome by Proxy, where people harm others to gain attention.
The BBC obtained copies of a letter sent to the families of Allitt's victims from the probation service, which said that, although offenders are entitled to apply for a review, it is not envisaged that many of the existing tariffs will be reduced.
Ms Burgess, who worked as a sister in outpatients, said: "I am surprised, in a way, that she felt she had a case to put in view of the harm she has done to the families, to the hospital and the staff at the hospital.
"In fact I am very dismayed that there is any possibility at all of her getting a lighter sentence. "
She added: "Looking at the lasting damage she has done to the hospital, let alone the fact she murdered four children and tried to murder nine more, I think her place is in prison for the rest of her life."
