A Sydney actor found guilty of killing a home invader with a samurai sword is performing lines and faking his teary apology, prosecutors say as sentencing looms.
Blake Davis, 31, was in December found guilty of the manslaughter of Jett McKee who he struck in the head with the sword after the ice-fuelled intruder fled his Forest Lodge unit on August 10, 2018.
Davis' girlfriend Hannah Quinn, 26, was also convicted of being an accessory after the fact to Mr McKee's manslaughter.
Speaking in court on Friday, Davis apologised to Mr McKee's family and friends, saying he would have done so earlier if his bail conditions had allowed him to contact them.
"I will never comprehend the pain you have gone through," Davis said.
"I don't expect you to accept my apology."
But Mr McKee's family wasn't buying his apology, saying he was feigning remorse to reduce his sentence.
In a victim impact statement, McKee's partner Averil Bowers told of her struggle to give birth to and raise their son after his death.
"When you took Jett's life, you didn't just end his existence, you robbed his son of a father (and) myself of a partner.
"(But) throughout this long and drawn-out ordeal, you have shockingly and disturbingly portrayed yourself as victims.
"I feel that you have used every tactic at your disposal to vindicate yourself while vilifying Jett."
McKee's parents both told the court they'd never recover from their son's violent killing.
"It was effortless to love him and cataclysmic to lose him," mother Lynn said.
"It is like being permanently winded, devoid of hope."
Had Davis felt any remorse, it should have been evident before now, McKee's family says.
Davis did not convince the crown prosecutor Chris Taylor either.
The Sydney actor told the court he'd been suicidal since the 2018 killing, and lived in fear.
"My only intention was to save Hannah," he said.
"My intention was never to harm this person or take his life."
Citing his acting training, Mr Taylor accused Davis of performing.
"Did that course involved learning a script and learning how to deliver it? That's what you've done here today isn't it?"
"There's no script for real life Mr Crown... It is just my truth of evidence," Davis countered.
"The evidence that you've given is not genuine evidence in many regards ... it is simply the recitation of what Your Honour might want to hear to better your position?" Mr Taylor said.
"No," Davis responded.
Mr Taylor suggested Davis could not remember if he intended to strike McKee on the head if he could not recall the attack.
He was lying about one or the other, and lying about his remorse.
"You're lying here today ... to assist your purpose," he argued.
Justice Natalie Adams will sentence Davis and Quinn at a later date.
