No Exit is famous for its memorable conclusion: "Hell is other people!" From an existentialist’s point of view, hell is other people because of competitive subjectivity. When two people are in a room together, they fight over who gets to be the subject and who is forced to be the object. When in the presence of others, one’s subjectivity, agency, and freedom will always be threatened, simply by the others’ gaze. For Sartre, the agony of this threat of objectification truly constitutes hell.
Inez is Sartre’s example of the human desire to be God in the search for ultimate subjectivity.
