"Other people" are actually not hell. Garcin is confused about why he is still in hell. Not that other people are hell; from the juvenile perspective he has on himself it prevents him from escaping hell. Even Inez won't leave though she is the closest to getting it.Hell is other people? I make my own hell with my thoughts and actions?
ok but here's the thing you'll need to watch that play and consider the actors, their morality, relative understanding of themselves and there is a sociological concept that's important to understand going on in this play. I don't want to really ruin it but... hell is actually inside of our minds when we employ the looking mirror self beyond a certain age obsessively as these people do. Inez is closest to escaping it but due to her amoral state (Garcin tried being moral but was immoral in life; in between; Estelle, on the left is vapid and clueless and not immoral to me).You suggested Sartre before to me
