A Victorian judge who jailed two skinheads for bashing an Asian student until he was "unrecognisable as a human being" says society needs to work out why there are so many angry young men.
Justice Betty King said racial hatred played a minor part in the "remorseless, violent and sustained" attack on the Vietnamese student who was set upon as he was walking home from work listening to music at Ascot Vale, in Melbourne's northwest, on June 27.
In jailing Shannon Hudson, 21, and Wayne O'Brien, 20, in the Victorian Supreme Court on Wednesday, Justice King said the men appeared to be angry not just at people from other countries, but the world at large.
"The increasing anger being displayed by young members of our community is one that is hard to fathom," she said.
"I am of the view that a lot of your discussions and talk about skinheads and white supremacy, and your Heil Hitler signs, were not really understood by either of you.
"It is my view that this attack would in all likelihood have occurred irrespective of the nationality of the person walking down the street.
"At some stage our society needs to work out why there are so many angry and unhappy young people, particularly males."
Hudson, O'Brien and a teenager who cannot be named knocked their unsuspecting victim to the ground, calling him a "yellow dog" and "f***ing gook" while repeatedly stabbing, kicking and punching his head and body until he fell unconscious.
Hudson then smashed a brick over his head, in what Justice King described as a "particularly chilling episode of violence".
O'Brien, who was staying with Hudson in Ascot Vale at the time, told police they were part of a neo-Nazi skinhead group called the Crazy Whiteboys that disliked Asians, Jews and "Negros".
The pair pleaded guilty to intentionally causing serious injury during the attack that left their victim fighting for life in a pool of blood with multiple skull and spine fractures and stab wounds that penetrated his bowel.
He has had plastic surgery, facial reconstruction surgery, dental work to replace lost teeth and has trouble speaking as a result of the damage to his jaw.
Justice King said photographs of the injuries were "horrendous".
"He is almost unrecognisable as a human being," she said.
Hudson was jailed for 10 and a half years with an eight-year minimum after Justice King said he had an "horrific" criminal record and was at high risk of reoffending.
O'Brien was jailed for four and a half years, with a two and a half year minimum.
The third offender has been dealt with in the children's court.
