Confessed Oslo madman Anders Behring Breivik who murdered 85 people – many of whom were young children — believes his actions “were necessary”. 

Breivik said he believed the actions were atrocious, but that in his head they were necessary," his lawyer Geir Lippestad said.

The 32-year-old owner of an organic farming company was on a "crusade" against the spread of Islam in Europe.

With a total of 92 confirmed killed, the attack is the deadliest by a single gunman in recorded history.

At his targeted summer camp on an island off Norway's coast, children ran into the sea in desperate attempts to escape Breivik, who fired on them for an estimated 90 minutes before police got to the scene. .  

There are seven children still missing.

"I heard screams.  I heard people begging for their lives and I heard shots. He just blew them away," Erik Kursetgjerde, 18, told Reuters.

Breivik is also charged with setting off a bomb blast that killed seven in Norway's capitol, Oslo. 

It's unclear if he's also confessed to that crime, reported.

Breivik is said to have launched his hate torn kill spree as a way of publicizing his “manifesto”.

Another crazed killer with an Aryan Nation manifesto — Adolf Hitler.
