I'm personally relieved that he was declared to be liable for his actions, even though that's clearly what he wanted. I'd much rather see him become a martyr figure to a tiny minority of idiots who're going to be socially and politically ostracized for voicing those opinions anyway, than to see any political ideology, no matter how extreme, be treated as a mental disorder in our courts. Because THAT is a slippery slope, and Norway already has a bit of shady history in that regard.
Don't misunderstand me, I feel privileged to be a Norwegian, and I'm proud of a lot of things about my country - but I'm honestly uncomfortable with the fact that we have a court system that has the right to take away people's ownership of their own actions in the first place. Sane or insane, if you don't own your actions, what do you own? Not being held responsible for what I do would feel the same to me as not being acknowledged as a person, but just as a thing. If I were ever tried in court for something, and ended up being declared not liable for my own actions, that would feel like stepping into something imagined by Kafka.
