Terapia di gruppo per serial killer

The way the characters interact in the group felt so authentic and tense. I'm curious whether this was based on real therapy practices or purely fictionalized.

The book made me question how much we can understand or empathize with people who commit terrible acts. Did others experience that moral dilemma?

The concept is so unique and darkly compelling. Wondering what sparked the idea to bring these characters into a shared space like this.
