THE violent inmate who attacked the killer of Daniel Morcombe with scalding hot water over him, has been released on parole.

Adam Paul Davidson's taste of freedom comes just weeks after he was sentenced to three months' jail for torturing Brett Peter Cowan, who is serving a life sentence for the abduction and murder of the Sunshine Coast schoolboy.

The father-of-four pleaded guilty to torturing the child killer when they were both serving time at the Wolston Correctional Centre in Wacol in 2016.

Cowan was doused in boiling water as he was playing cards.

Davidson had filled a mop bucket from a hot water urn. He said Cowan deserved "a little bit of retribution" and he wanted "to be a voice for Daniel because he could not speak out".

Cowan suffered superficial burns and has since fully recovered.

Brisbane District Court Judge Ian Dearden said he would "take a chance" on Davidson - in jail for fraud and robbery offences - and grant him early release.

Even so, Davidson will be closely supervised and may have to wear electronic monitoring and obey curfews.

Daniel's remains were discovered in August 2011 after a major undercover police operation encouraged Cowan to tell of his involvement in kidnapping and killing the young teen in 2003.
