What are the motifs in Without Conscience: The Disturbing World of the Psychopaths Among Us by Robert D. Hare?

Another interesting topic that Hare explores is the lives of victims of psychopaths. He points out that sometimes victims are family members (especially parents and siblings) who are at a loss for options. They are the people who may have noticed that there was some sort of disorder with their family member from a very young age. It is especially hard to be a parent and deal with a child who is a psychopath. The parent feels a duty to care and treat their child, but has no idea what to do when their child is threatening others, exhibiting violence, and committing horrible acts with little remorse or care.
