Explore the concepts of angst or anguish, authenticity, and bad faith through a discussion of the philosophical views of Kierkegaard, Heidegger, and Sartre and use an original example either from your own life experience or from a work of fiction or film to illustrate your discussion. Which of these three existentialist thinkers most closely captures your own approach to living an ethical life (or at least attempting to do so)? Explain and defend your answer using whatever evidence you believe to be relevant.
