"Địa ngục không tồn tại."
Translation:Hell does not exist.
"l'enfer, c'est les autres" might have been said by a famous misanthrope, but Sartre himself said it has been so often misinterpreted as the relationships we have with others are all poisonous, hellish. however, he actually meant that, if the relationship with someone is spoiled or twisted, that person then couldn't be none other than your hell. they are the ones who make you be conscious of yourself, they judge you, criticize you. whether you want it or not, your self-conscious is more or less affected by how others see you. (very loose translation of a comment from Sartre about Huis clos)
ps. Huis clos is a play written by Jean-Paul Sartre in which three protagonists arrived in hell after their death. they are locked together in a plain room, without any torture devices they've all expected. at first, they are unwilling to share their stories that have brought them there. soon enough their backgrounds get uncovered: infidelity, torture, infanticide, pushing others to commit suicide, etc. they despise each other, but they still need the other ones. they become the others' hell, their own executioners, for eternity.
