What is the author's tone in Without Conscience: The Disturbing World of the Psychopaths Among Us by Robert D. Hare?

To Hare's credit, he tries his best to stay away from psychological jargon. This is not a book geared toward other psychologists, and thus the tone is not pompous or scholarly. It seems to be more focused on warning lay people about the threat of psychopaths. When Hare is clarifying the difference between different psychological terms, he takes his time and makes sure that the reader truly understands what he is talking about.
