The crime emerged after police discovered three screenshots from a video that Honeyman had filmed and sent to another man.
One showed a man lying in the foetal position, covered in blood and wearing only socks.
During the trial, Honeyman had accepted causing the death, but had denied murder.
Following the guilty verdict, the court also heard Honeyman had been previously jailed for almost three years after an attack on Lawson in 2022.
Sentencing, Lord Arthurson told Honeyman: “This crime was exceptionally callous.
“The violence was designed to cause him particular pain and were nothing less than acts of torture.
“The screenshots shown in court taken from the video in the house of you and your victim made clear that you revelled in what you had done.
“The image of you half naked and smeared in the victim’s blood was resonant of a scene from sort of dystopian work of fiction.”
The judge added that everyone who assisted Honeyman after the murder “should be thoroughly ashamed.”
Det Ch Insp Ally Semple said: “This was a shocking and violent attack which has been devastating for the family and friends of Alan Lawson.
“Honeyman will now face the consequences of his actions.
“While no outcome can truly ease the pain of losing Alan, we hope this conviction and sentencing will bring some comfort to his loved ones.
