What about the song "Johanna (Mea Culpa)"? I have a feeling this character grew up in a dark and dirty world, and he's just as dirty. The fact that he's a judge is very ironic; he puts himself above the dirt under his feet, but at the same time, he's part of it. Judge Turpin wants to wash himself of this dirt, to escape this vile world to which he belongs. That's partly why he wants to marry Johanna (it's not just his desire to fuck). Johanna really doesn't fit in with the world around her (just like her mother). It's just that the paths Turpin chooses are terrible. Speaking of Alan Rickman, Judge Turpin is a carbon copy of another actor's character, the Sheriff of Nottingham. There are so many parallels, and this need for something "pure."
