The self-named ‘Bind, Torture, Kill’ murderer terrorised the Kansas city of Wichita for years, and received a life sentence for each of his victims, in an emotionally-charged court hearing.
The 60-year-old former church congregation president and Boy Scout leader will not be eligible for parole for at least 40 years.
The brutal murders were carried out between 1974 and 1991.
Rader was arrested in February and pleaded guilty in June to stalking, torturing and killing seven women, two children and one man.
He could not be sentenced to death because the killings were committed before Kansas reintroduced capital punishment in 1994.
In a rambling and disjointed statement, Rader faced his victims’ relatives and addressed the judge and the families.
He called himself a Christian and quoted a Bible verse that talked about demons, referring to them as “factor X” which drove him to torture and kill.
“Today is my final judgment,” he said, as well as praising the work of police and apologised to the victims’ relatives.
“There was no way I was going to get out of this,” he said.
“I hope some day God will accept me. The dark side was there but now I think light is beginning to shine,” he told the judge.
Wiping away tears, said his two children and his ex-wife, who divorced him last month, were his final victims.
However prosecutor Nola Foulston remained unmoved, saying Rader was shedding “crocodile tears.”
Earlier, law enforcement agents testified at the second day of his sentencing hearing that Rader had a lifetime obsession with sexual bondage and torture and kept souvenirs of his 10 victims to remember the thrill the crimes gave him.
Police officials testified that he collected underwear from women he killed and wrote stories and poems about the killings.
The relatives of Rader’s victims gave emotional testimony, tearfully telling the court Rader had deprived them of their loved ones.
