HELP!!- The book No Exit

Hi I am writing a research paper on the book No Exit. I will be examining the way Sartre shows people being punished for how they have lived and how they are living now by being doomed to an existential hell. What is Existentialism? What is bad faith? How do bad faith and Existentialism apply to No Exit? What features of hell function as traps which take away free will and identity? How do each of the three characters fail at being authentic? What do each of the three characters come to realize about their prospects at the end of the day? Any help would be GREATLY appreciated! THANKS

I think you should analyze your own questions as you seem to be asking the right questions.
