This book has some vauable insights: that the source of "evil" is lying, a refusal to self reflect, and narcissism, but I believe the term "evil" is frighteningly simplistic. For true healing to take place, judgement must be suspended. If a therapist judges a person as evil, whether it be the client or the client's parent, I cannot see how the client can be helped. If the purpose of this book is to protect oneself against evil by being able to define and recognize it, then it only serves to encourage closed thinking.
