think about the show as a real alternate world. what happens in that world will happen regardless of what we think or say or feel, or what's being discussed in the public eye right now etc etc. cooper was pulled into a van, woke up and found himself tied to a pillar in the jungle with a group of people just letting him stand there tied to the pillar, then he wakes up inside an old wooden ship. it's hot everywhere. cooper's proposal that he is in hell is not an unrealistic observation, and it would actually suck more if the producers systematically avoided certain subjects because they have been touched on before. for cooper it was completely natural to think he was in hell because that's what it felt like to him. regardless of what some people have theorized about the show or what the producers have said.Lindelof confirmed that the purgatory theory isn't true a while back, I don't know why they brought it up in this episode.
this is all just a guess btw
