this guy belongs to the clique of people who know very little apart from physical violence
his whole life has probably been exposed to & subject to violence
this violence is endemic in society, beginning from the social economic violence that resulted in the 1st Fleet of convicts sailing to this land
Australia is a very cold & individualist society
I recall when I first travelled across Indonesia. Indonesian men & grandmothers were constantly touching me, hugging me, holding my hand, massaging my arms, sleeping on me in the bus, etc
Many cultures, including European, have are far greater social orientation that the cold individualism of British culture born from its ECONOMIC imperialism
therefore, it is the "right wing" hardmen that give rise to the underlying problem & seek the maximum punishment to cover up themselves
if our society was more loving at large, then these crimes would be less
thus, the "left wing" are not excusing these crimes but trying to create more understanding & a better society so these crimes are less
