That depends. The execution of Quisling and the top leaders in the NS i think is viewed fairly possitive. People like police chief Jonas Lie wanted to contiune to fight in Norway because he knew that when the war was ended his days would be numbered. He was one of the most hated people in Quislings goverment, perhaps second only to Quisling himself. Jonas Lie most liekly drank himself to death on a farm after the war had ended and he and some friends had taken refuge there and where negoiating with the resistance about a surrender. One of the men there, Sværre Riisnæs had been chief of justice in Quislings gouverment and actually managed to fake himself so insane that the case against him had to be dropped and he got sent to a mental institute instead. After getting released from there he actually spent some time in a monestery in Sicily
However, i think something that people look back on with a certain shame is the treatment of soldiers who voluntered to fight on the eastern front, and especially front line nurses. After the war about 400-500 nurses who had served in the German Red Cross got convictions for working with the enemy. And while "poor working class men" had gotten sentenced for fighting on the eastern front, almost noboddy got sentenced for profitereing from the war. Those who made money from working with the Germans got away easily, and a large part of Norwegian industry colobaderated with the Germans making supplies for the German Army.
Also right after the war there was a large hatredt towards those who had worked for the Germans and the NS. Sentences giving right after the war where stricter then those given later, as people got more of a "distance" between it.
Today i guess it still is a tocuhy subject. Those who fought on the eastern front are viewed more mildly. 4898 of them got sentenced for "Treason towards the country" instead of their actions in the Germany army. They usually lost their voting rights for a period of years and where forbidden from working in gouverment positions.
Those who where nurses on the easter front have later been given a "formal apology" and today i dont think anyone has any kind of resentment toward them. Event those who fought as soldiers on the eastern front are viewed much more favorebly then those who worked with the Germans in Norway providing supplies,weapons,ratting out resistance members and such.
I'm sorry if this seems like along list of babble that makes no sense. We had a lecture about it not long ago but i don't have my notes here.
