Vicente Hilario was sentenced to life in prison Tuesday for an execution-style murder.
He refused to go quietly, and at one point, was kicked out of the courtroom.
The father of victim Aureo Arick Moore also had his turn to speak.
"I was very angry at Vincente and I hated Vincente for quite a while but I've come to the point to forgive Vincent and I hope Vincente can find peace in his life and his family," said Robert Moore.
In March, a jury found Hilario, 26, guilty of first-degree murder.
Evidence in the trial showed Hilario shot Moore six times in an effort to prevent Moore from testifying against his friend, Kyle Akau, in a case involving an armed robbery in the Kapaa Safeway parking lot.
"I think the prosecutor's office and the police have helped further a lie," Hilario said in court. "I think Mr. Moore had no right to be angry with me because I didn't kill his son. I didn't rob his son. I think it's a perversion of justice and people should be sick to know there are prosecuting attorneys that helped a murderer go free and frame me. I'm not responsible for killing this person."
Later in court,Chief Judge Randal Valenciano said the criminal justice system cannot work if witnesses are intimidated or bribed, referencing Hilario's other conviction for bribing a witness.
To that, Hilario said, "Excuse me, your honor. Do you think it works when we accept lies as the truth?"
After a few more comments to the judge, Hilario was ordered out of the courtroom.
He was sentenced to life without parole.
