Watch this exchange from Playing Dead Episode 8 from this point to 07:08.
The developers specifically explain that saving or dropping Ben is your chance to make the same moral choice as the people of Crawford: Protect or abandon the "weak." If you drop him then you are like the people of Crawford, and you are giving up your humanity.
Please don't get mad at me though, this is "word of God" as TV Tropes puts it.
Anyway, I'm going to call this kind of thing the "Episode Choice."
Are there other examples of this? I think so and here are my guesses.
Episode 1: I think this episode is about whether you help someone or not. Clem is the first one to help Lee, basically saving him from the babysitter. Hershel's an uptight prick who won't help a bunch of able-bodied people who could have made his farm more defensible. Kenny is either helpful or unhelpful depending on the time of day. Larry and Lilly are just vile. Carley/Doug are likable and brave and therefore the center of one of the two Choices in this episode.
1) Save Carley or Doug.
Moral: You can't save everyone.
2) Help Irene kill herself.
Moral: Sometimes helping someone means ending their misery.
Episode 2: For reasons that I think are obvious, I feel this one is about taking advantage of others for your own benefit.
This is another obvious one: To Kill or not to kill Danny. Danny nearly breaks the fourth wall to explain it, telling Lee to keep him alive so the meat is fresh (which I don't exactly get, but whatever).
Moral: The human thing to do is to not victimize people indiscriminately for your own gain.
I think this is also true, in a toned-down form, of the station wagon choice. Looting those peoples' supplies was essentially the same.
Episode 3: This is a toughie. Ben and Lily seem like the main "suspects" here since they caused all the trouble, and both may have been misguided attempts to do the right thing. I guess the moral here is don't do shit to "help" without consulting your friends first?
Episode 4: Discussed above.
Episode 5: I think the episode question is whether you have Clem shoot Lee or not, and given that the rest of the episode is about selflessness (Kenny even gives a speech in one version about how his heart grew three sizes that day) I think it fits. Personally, I think asking Clem to shoot Lee is the selfish answer, but I'm aware others think it's a necessary lesson for her. I deeply disagree with them, but there it is.
Moral: The human thing to do is to think of others before yourself.
Anyway, I think we all just played through a big psychological test on the nature of human nature.
