On 22 July 2011, he killed eight people by detonating a van bomb amid Regjeringskvartalet in Oslo, then shot dead 69 participants of a Workers' Youth League (AUF) summer camp on the island of Utøya. In July 2012, he was convicted of mass murder, causing a fatal explosion, and terrorism.
On 24 August 2012, Breivik was adjudged sane and sentenced to containment—a special form of a prison sentence that can be extended indefinitely; with an approximate period of 21 years and a minimum time of 10 years, the maximum penalty in Norway. Breivik did not appeal and on 8 September media announced that the verdict was final.
Anders Behring Breivik, Wikipedia
I don't get it: he killed 77 people, but these murders were combined into a single crime "mass murder". It's like he gets a discount. Sure, it's the maximum penalty, but shouldn't he have received 77 penalties?
Question: After killing 77 people, why was Anders Behring Breivik not convicted of 77 murders?
Planned murder is punished with up to 21 years of imprisonment, regardless of the number of murder victims.
