Fascinating read about psychopathy and how it originates, how it is characterized, how it develops, and it's causes. Combined with the addition of interesting but unsettling examples of real life cases highlight how important and influential research into psychopathy is. Critically it was a bit repetitive on occasions but it was an interesting read, easily understandable for a casual reader but provided further reading that I will hopefully venture into. I would definitely recommend it to those interested in understanding psychopaths and the study of them.
