Then the only thing exaggerated is your interpretation of it. Although, honestly, it doesn't seem that way at all to me. I see proof of it being "general fear" (as I interpret that) everyday with my two little sisters. Without the parents around they always hold our parents' judgment against each other to prevent them from doing something. They also get really upset (very quickly as well) when, after something is done by one, the other claims to have the intention to bring this to the authority figure's judgment.
This is furthered when the parents are actually around. When these promises follow through, or when a guardian catches one having done something considered wrong, they are very quick to lie about it, in fact it is their first reaction. They aren't malicious, evil children, but their natural instinct is to hide in order to avoid punishment. I've even seen just yesterday a case of one using misdirection to try and avoid punishment, attempting to hide their own "wrong" by bringing light to a completely off-topic "wrong" done by the other sister. They do not have ill will towards each other any other time and get along and love each other, but the taboos that are created by punishments being associated with things does indeed create a state of fear that bends them. They aren't constantly being afraid, if for whatever reason that is your concept of "general fear", which I feel no one has, for people only experience fear when their mind is associated with some sort of possibility, it exists only relative to some circumstance.
That fact is also why this stage of morality shouldn't be used in such a way because, as mentioned in my previous post, people when given the right circumstances, will justify their actions. This holds true when people feel that they can do something without retaliation or without being judged. If someone thinks that way, when put in a situation where they are in the dark, where judgment can't pierce them, temptation will grab a hold of them much more than someone who has a more empathetic understanding of morality. Not that we should act as if some sort of authoritative figure it always watching us, even alone in the darkness, but rather an understanding of consequences separate of the concept of judgment entirely.
