Answer:
I am not sure of the dialogue that you want to include, but you must remember that even though aliens want to take over the world and they want to observe the human behavior - they see that the people are their own worst enemy. They want to turn on each other and they have self-destructive behaviors. They are ending themselves.
Explanation:
This story was used to describe how to speak out against the social structure of the day. Fear is the culprit that causes these people to turn on themselves and each other. They begin to notice all of the flaws within themselves and the fear eats at them constantly.
They pick the most dangerous enemy they can find, and its themselves.
