Infamous Moors murderer Ian Brady says he wants to starve himself to death and described the killing of five children as a "recreational and existential" experience.
Brady, 75, has spent the past 47 years behind bars for the murder of five children aged 10 to 17 with his accomplice Myra Hindley in the 1960s.
According to the Daily Mail, at his Manchester mental health tribunal, he compared the killings to the acts of soldiers and politicians.
"A criminal in a pursuit of crime is going to gain from the crime," he said.
"He has given a value to the person he is about to kill."
He was asked: "What value did you get?"
Brady replied: "Existential experience."
It is the first time he spoken at length since he was jailed in 1966.
Throughout the early '60s he and Hindley, who died imprisoned but in hospital in 2002, would lure children and sexually torture them, before killing them and burying them on the Yorkshire moors.
Pauline Reade, 16, disappeared on her way to a disco on July 12, 1963 and John Kilbride, 12, vanished in November that year.
Keith Bennett was taken on June 16, 1964 after he left home to visit his grandmother, while 10-year-old Lesley Ann Downey was lured away from a fun fair on Boxing Day, 1964. Edward Evans, 17, was killed in October 1965.
Brady received life sentences for the murders of John, Lesley Ann and Edward.
Hindley was convicted of killing Lesley Ann and Edward and shielding Brady after John's murder, and jailed for life.
After their sentencing the pair confessed to killing Pauline and Keith. Pauline's body was discovered in 1987, but Keith's body has never been found.
Brady, now 75, is seeking to return to jail, rather than stay in the high security Ashworth Hospital where he has been held since 1983, the Mail reported.
He said he wanted to return to prison so he could starve himself to death. He is being fed via a tube through his nose at hospital.
Despite being one of Britain's most depraved serial killers Brady denied he was mentally ill.
Instead, he likened his actions to "method acting".
His lawyer asked Brady how he explained supposed hallucinations and episodes of him talking to himself.
"Well, first of all - prison," Brady replied.
"If I interact with the TV, Tony Blair or something on, and make any comment, this is interpreted as psychosis.
"I was in solitary confinement for a time. I would memorise whole pages of Shakespeare and Plato and other people and recite them all to myself while walking up and down exercising in the cell.
"And er, who doesn't talk to themselves? This is a question people very rarely ask."
