Die große Enzyklopädie der Serienmörder

The psychological insights add depth but also make the book feel more like a study than just a list. I wonder what motivated this approach and how it influences the reader's understanding.

The encyclopedia covers so many killers that it was almost dizzying. Did others find it informative or did the volume make it hard to connect with individual stories?

With so many cases, I’m curious about the selection criteria—was it based on notoriety, impact, or available information?
