“He has said he believed the actions were atrocious, but that in his head they were necessary,” his lawyer Geir Lippestad said.
Breivik initially posted a manifesto on the Internet just hours before the attack, calling for the “elimination of Muslims” in Europe.
According to the 1,500-page tract, titled 2083: A European Declaration of Independence, Behring had actively prepared the operation since the fall of 2009.
In the document, the 32-year-old Norwegian revealed that he had acquired explosives and even tested a bomb on June 13, presenting himself as a far-right nationalist determined to eliminate “Muslims, Marxists and multiculturalists” in Europe.
He detailed the preparations for his actions, arguing for “the use of terrorism as a means to awaken the masses,” and said that he expected to be perceived as “the biggest (Nazi- ) monster ever witnessed since WW2.”
“Muslims must be considered as wild animals,” he wrote in the manifesto. “Do not blame the wild animals but rather the multiculturalist category A and B traitors who allowed these animals to enter our lands, and continue to facilitate them,” Breivik wrote, explaining that “category A and B traitors” include politicians and journalists.
The author of the attacks in Norway had no criminal record, he was in a shooting club and used legal firearms in the attack.
At the end of the manifesto Breivik states, “I believe this will be my last entry. It is now Fri July 22nd, 12.51. Sincere regards, Andrew Berwick. Justiciar Knight Commander. Knights Templar Europe. Knights Templar Norway.”
