Existential psychology offers a unique insight into the loneliness and isolation that often are experienced by those who contemplate violence. These individuals become isolated from society, fearful of their own death, and overwhelmed with the freedom of choice, and they are unable to find any greater purpose or meaning in life. This chapter introduces Caleb as a case study to illustrate the treatment concepts provided by existentialism. It discusses Yalom's work in existential psychotherapy in terms of helping the client feel empowered and addresses the themes of freedom, death, isolation, and meaninglessness. Perls offered insight through his work in gestalt therapy. The goal of gestalt therapy is awareness, to assist clients in gaining moment‐to‐moment awareness and greater choice. The chapter describes core concepts such as the empty chair, internal dialogue, exaggeration, and staying with the feeling as practical treatment examples.
