A Perth man who stabbed a young father through the heart has been jailed for life - beginning his long sentence the day before his mother is due to be released for a murder she committed nearly twenty years ago.

Michael Patrick Walker, 24, stabbed Axel Boreski seven times with a paring knife in Mandurah 2017.

The violent attack only ended after the blade hit bone and broke.

Today the Supreme Court was told the stabbing was motivated by revenge, and that Walker lashed out in a "dis-inhibited act of explosive rage", he was drunk and humiliated after losing a fist fight to Mr Boreski, who he'd only met that night.

Walker had claimed he stabbed the 27-year-old in self defence, but the jury disagreed after the court was played a Triple Zero call made by Walker, where he said he was going to stab Mr Boreski, and kill him. He then grabbed a knife, followed him down the street, and did exactly that.

Walkers lawyer said his client, who had no prior criminal record, had vowed he didn't want to end up like his mother, but instead had turned out to be just like her.

Justice Anthony Derrick said while he had taken Walkers youth and family background into consideration, he had to send a message to the community that alcohol-fuelled violence would not be tolerated.

Outside court, Mr Boreski's grandfather Murray Hayward agreed.

"Please young people stay away from the alcohol-fuelled violence. It's shocking, this is how things end up which is no good for anybody, particularly families, stop it please. He was our first grandson...we'll miss him terribly every day."
