The 15-year-old schoolboy was allegedly abducted from Pollokshields in Glasgow, stabbed and set on fire in 2004.
Summing up, advocate depute Mark Stewart said the accused had condemned themselves "from their own mouths".
Mohammed Faisal Mushtaq, 27, Zeeshan Shahid, 28, and Imran Shahid, 29, deny racially aggravated murder.
During more than four weeks of evidence at the High Court in Edinburgh, the trial has heard prosecution claims that Kriss, 15, was snatched from the street in Pollokshields, driven to Dundee and back in a silver Mercedes before being stabbed, doused with petrol and set on file.
His burned and bloodied body was found beside the Clyde Walkway near Celtic's training ground on the morning of 16 March 2004.
The three accused men, who blame others for the death, were brought back from Pakistan to stand trial.
Mr Stewart said: "That crime can be described as one of the worst and most appalling crimes of inhumanity against an effectively defenceless boy."
The lawyer claimed that forensic, technical and eye-witness evidence about the events of 15 March 2004, including alleged attempts at a cover-up, proved his case.
He said the three men had also "disappeared abroad in an attempt to avoid detection".
Mr Stewart also said they had condemned themselves "from their own mouths" by what they had said about their intentions when they were setting out, statements during the crime itself and admissions of responsibility afterwards.
Zahid Mohammed, 22, served half of a five year jail sentence for assaulting Kriss and lying to police - then returned to court to give evidence against the three men now on trial.
Mr Stewart said the men had "condemned themselves"
Mr Stewart reminded the jury of nine women and six men how Zahid Mohammed had told of Imran Shahid's "unreasonable and extraordinary rage and thirst for vengeance" which had followed an alleged incident in a Glasgow night club.
Mr Shahid blamed "white boys" from McCulloch Street, Pollokshields, for a bottle attack and threatened to "chop them up and take their eyes out."
"It is clear, ladies and gentlemen, this enterprise had a racist motive," Mr Stewart said.
He announced that he was dropping a number of less serious charges against the three men to "clear the decks" and allow the jury to focus on the abduction and murder allegations.
On Friday the jury will hear from defence counsels for each of the three accused men.
