Serial killer - Le côté sombre de la nature humaine

I found the mix of well-known cases and obscure stories fascinating. Did the author aim to shed light on overlooked aspects of serial killer history?

The detailed insights into their minds made me question how much of their psychology is nature versus nurture. Was that the author's intention?

The book seamlessly weaves between stories and analysis, which kept me engaged. I'm curious whether this structure was planned from the start or developed during writing.
