(j) The Prisoner Review Board shall not parole the eligible person if it determines that:
(1) there is a substantial risk that the eligible person will not conform to reasonable conditions of parole or aftercare release; or
(2) the eligible person's release at that time would deprecate the seriousness of his or her offense or promote disrespect for the law; or
(3) the eligible person's release would have a substantially adverse effect on institutional discipline.
In considering the factors affecting the release determination under 20 Ill. Adm. Code 1610.50(b), the Prisoner Review Board panel shall consider the diminished culpability of youthful offenders, the hallmark features of youth, and any subsequent growth and maturity of the youthful offender during incarceration.
