In the Annotated Pratchett, the entry for Night Watch outlines parallels with Les Miserables, and a point is brought up which states:

“Javert, the policeman in LM, is concerned only with justice, which he defines as the punishment of the guilty. Vimes, the policeman in NW, is equally obsessed by justice, but he defines it as the protection of the innocent.”, which I think is an interesting distinction and which seems to be relevant now.

John Darnielle: I hate to say this, because, I don’t want to wish death on anybody, but.. it’s wonderful when your abuser dies. It’s wonderful. It’s like nothing in the world. It’s like, you are free. There’s a feeling that you will never be free of what you were. You know, there’s that. But there is this, you know, even though my stepfather was helpless at the end of his life, but to know that the person who used to hurt you no longer can. It’s very, very, very deep. It’s unbelievable.

Interviewer: Do you forgive him?

John Darnielle: No.
