From what I think this kind of behavior is a coping mechanism.
The government made it very clear that everyone was a criminal who showed signs of disobedience. Since that had being made clear right from the start, and since it is or being thought painful to be treated and seen as a criminal the human starts to cope with the situation in a way he can handle.
In order to handle pain and being outcasted, you need to have experienced pain, despair or even marginalisation before such an event. To know that it is not the end of the world. The tougher, the better, I'd say. Even though this sounds like a contradiction.
I wish I hadn't seen so much of it ...
me, neither.
Whatever that might be good for...
