Warsaw may have been suggesting that once imprisoned he should not have been isolated and just in the general cells then the 'lads' could have beaten the shit out of him and hopefully had him killed
From Wikipedia, looks like he served a mixture of prison and mental hospital but was attacked on numerous occasions so i doubt he had an easy ride and logically must have been in fear at least some of the time
Custody
Prison and Broadmoor Hospital
Following his conviction and incarceration, Sutcliffe chose to use the name Coonan, his mother's maiden name.[65] He began his sentence at HMP Parkhurst on 22 May 1981. Despite being found sane at his trial, he was diagnosed with paranoid schizophrenia. Attempts to send him to a secure psychiatric unit were blocked. While at Parkhurst he was seriously assaulted by James Costello, a 35-year-old career criminal with several convictions for violence. On 10 January 1983, he followed Sutcliffe into the recess of F2, the hospital wing at Parkhurst Prison, and plunged a broken coffee jar twice into the left side of Sutcliffe's face, creating four wounds requiring 30 stitches.[66] In March 1984 Sutcliffe was sent to Broadmoor Hospital, under Section 47 of the Mental Health Act 1983.[67]
His wife obtained a separation from him in 1982 and a divorce in April 1994. On 23 February 1996, Sutcliffe was attacked in his room in Broadmoor Hospital's Henley Ward. Paul Wilson, a convicted robber, asked to borrow a videotape before attempting to strangle him with the cable from a pair of stereo headphones. Two other convicted murderers, Kenneth Erskine and Jamie Devitt, intervened on hearing screams.[66]
After an attack with a pen by fellow inmate Ian Kay on 10 March 1997, Sutcliffe lost the vision in his left eye, and his right eye was severely damaged.[68] Kay admitted trying to kill Sutcliffe, and was ordered to be detained in a secure mental hospital without limit of time.[69] In 2003 it was reported that Sutcliffe had developed diabetes.[70]
Sutcliffe's father died in 2004 and was cremated. On 17 January 2005 Sutcliffe was allowed to visit Grange-over-Sands where the ashes had been scattered. The decision to allow the temporary release was initiated by David Blunkett and ratified by Charles Clarke when he became Home Secretary. Sutcliffe was accompanied by four members of the hospital staff. Despite the passage of 25 years since the Ripper murders, Sutcliffe's visit was the focus of front-page tabloid headlines.[71]
On 22 December 2007, Sutcliffe was attacked by fellow inmate Patrick Sureda, who lunged at him with a metal cutlery knife while shouting "You fucking raping, murdering bastard, I'll blind your fucking other one". Sutcliffe flung himself backwards and the blade missed his right eye, stabbing him in the cheek.[72]
On 17 February 2009, it was reported[73] that Sutcliffe was "fit to leave Broadmoor". On 23 March 2010, the Secretary of State for Justice, Jack Straw, was questioned by Julie Kirkbride, Conservative MP for Bromsgrove, in the House of Commons seeking reassurance for a constituent, a victim of Sutcliffe, that he would remain in prison. Straw responded that whilst the matter of Sutcliffe's release was a parole board matter, "that all the evidence that I have seen on this case, and it's a great deal, suggests to me that there are no circumstances in which this man will be released
