Who is Robert D. Hare from Without Conscience: The Disturbing World of the Psychopaths Among Us and what is their importance?

The entire book is told from the perspective of Robert D. Hare, a Canadian psychologist and researcher of psychopathy. Hare has decided to write this book to shed light on the many psychopaths that live among all of us from day to day. Hare does this by using evidence from case studies, stories passed on to him, and notorious serial killers. Hare's narrative is great to read because he is very humble. He admits to being taken in by psychopaths, which makes him extremely likable to the reader.
