Alexander Villaluna knifed his ex-partner and brutally murdered her new date as they dined at a Sydney restaurant because of his "twisted belief that she was his property".
"The attack was savage, cowardly and undertaken without hesitation", Justice Robert Beech-Jones said when sentencing Villaluna to 40 years in jail with a non-parole period of 30 years at the NSW Supreme Court on Thursday.
"His victim did nothing more than meet a woman for a dinner date."
Villaluna, 45, previously pleaded guilty to murdering Keith Collins, 53, and wounding nurse Jovi Pilapil, 40, with intent to cause her grievous bodily harm in late March 2016.
The divorced father of four children and three step-children was on his first Tinder date with Ms Pilapil at the Kangan restaurant, at the Hornsby Westfield shopping centre, when he was stabbed 12 times.
CCTV footage shows Villaluna stabbed Mr Collins then stepped around the table and attacked Ms Pilapil before returning to kneel on Mr Collins' chest, as the dying man tried to roll away, so he could stab him again.
Villaluna then calmly walked out of the restaurant.
"Of all the cowardly and pitiless acts that the offender committed on this day, his actions in returning to finish off a dying man on the ground were the most heinous," Justice Beech-Jones said.
"Mr Collins must have been terrified as he realised his life was ebbing away."
Villaluna had been very possessive and jealous in his relationship with Ms Pilapil, which ended in November 2015, two months before she was granted an interim apprehended domestic violence order.
She'd been subject to "years of torment" from Villaluna, who had threatened to kill her if she ever started another relationship.
Justice Beech-Jones said Villaluna "is an almost textbook example of a perpetrator of extreme domestic violence".
"The attack upon Ms Pilapil and Mr Collins was a product of the offender's twisted belief that she was his property," he said.
He said Villaluna, who claimed he was "blinded by love" during the attack, wasn't remorseful.
"Instead he is awash with self-pity and anger borne of his sense of entitlement to control Ms Pilapil and kill anyone who came close to her."
Villaluna could reoffend "in the unlikely event that he ever forms another relationship," Justice Beech-Jones said.
Villaluna will be eligible for parole in 2046.
