Maybe all Hannibal Lecter needed was a hug and a friend...
Chapter 16 gives a rundown of the many different biological and psychological approaches to helping people who experience psychological disorders.
One of the most interesting sections (albiet short) that I found in chapter 16 describes a type of therapy called, "Person Centered Therapy." What sets this type of treatment aside from others is that the therapist doesn't try to define/diagnose the client's problems or even suggest a treatment. Rather, the therapist fills the role of a genuine person, that reacts to what the client is relating. The therapist, has to show "unconditional positive regard," expressing empathy and understanding of the client's perspectives and emotions. In other words: the therapist has to be the client's best friend no matter what.
For what classifications of psychological disorders is Person-Centered therapy successful? Where might it fail to produce positive results- or possibly even endager the therapist or client?
So, the next time you come across someone who may have any combination of paranoid schizophrenia, antisocial personality disorder etc., and may have just eaten someone's liver- they might just need a hug and a friend- some good ole fashioned acceptance.
You pose some good questions in your post. Your example is extreme, but shows good application of critical thinking!
