Well, the story is set up to favor Universalism. If Moldbug had written it, probably it would have ended with Valjean concluding that his earlier philosophy contained a hopeless conflict between rejecting authority and helping people live happier lives.
I'm smirking at the idea of a Moldbuggian story of the uprising of 1832. Revolutionists Get What They Deserve or some-such. :)
But I don't think that story has room for the complex characters of Hugo's story, narratively speaking. There's no room at all for Valjean, and Javert becomes simply the protagonist to the evil antagonist Enjolras.
Ultimately, you asked if canon!Javert embodies Moldbug. As I suggested above, I think the answer is no. He's a tragic figure - even Hugo would admit that > 75% of the time, the king's law point toward a just outcome...
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
