He did things like buy books full of illustrations, took them apart entirely and sold each plate individually because this was essentially untraceable (IIRC). He was not lovingly restoring these books. He was a book predator and the object was financial gain.
My reaction is more to the idea of seeing this stuff and knowing the intent was not at all good. Kind of like the movie scene showing instruments that make it clear the Morlocks eat humans and these instruments are used to kill them, prepare them as meat, etc. I have no fear of, say, knives per se. But in a certain context, it becomes clear what the intent of the instrument is and this can be horrifying.
