I mean, if you think that isn't an insult to the victims, their families, etc.; if you don't think that's absolutely crazy, and I don't know what to tell you, man. Heck, if killing someone, let alone that many people, isn't so bad, why do we care about any other crime as much as we do? Why all this ridiculous outrage in the public square about all sorts real and imagined sins when life itself is so cheap?
Whatever the flaws in the American justice system (and there are many), Norwegian law and the sensibilities behind it are insane in this respect.
> sentences seem to be more about vengeance than about rehabilitation or making society safer.
Justice has more than one aim. Deterrence and rehabilitation are two of them, so is the preservation of social order. But justice is also retributive. Retribution isn't about hate, whatever modern confusion tells you. That's why we aim to have qualified impartial third-parties (judges) who are supposed to adjudicate such things instead of leaving things up to a hate-filled lynch mob, one that often confuses envy with anger at injustice.
