The Monsters are Due on Maple Street Theme: Mankind is its own worst enemy
It's true. He wakes up in the night to watch the stars. He didn't do anything wrong.
Well I see you sometimes come outside in the night and go look up at the sky, as if you were looking for something.
I have insomnia! I wake up and go look at the stars.
You killed Pete Van Horn Charlie!
Yes, know I see. They picked their worst enemy, themselves.
Now do you see why we turn off their power for a few hours.
In scene one where a women walks up to Les Goodman's porch to tell him she saw him staring at the sky in the early morning supports the theme that mankind is its own worst enemy. The women tells Les that she saw him outside in the early morning staring up at the sky. She says that she was up out of bed herself, so why isn't she blamed for being up so late at night and only Les is. She told everyone that Les was the only one that did that when she did it herself as well. In scene two where Charlie shots Pete Van Horn, this supports the topic, mankind is its own worst enemy. Charlie shots Pete out of "fear for his family and home". Charlie only said he shot Pete out of fear for his family an home so he would get out of trouble, but it back fired. Charlie still got blamed for shooting Pete, which he did. In the last scene where the aliens are talking, this is a example why mankind is its own worst enemy. One of the aliens was saying that the people on Maple Street choose their worst enemy, themselves. These examples all related to mankind is its own worst enemy.
Evidence one: A women walks up to Les Goodman and his wife and tell him what she saw him doing.
Evidence two: Charlie sees a dark figure in the shadows and shots it only to have it be Pete Van Horn.
Evidence three: The two aliens are talking how the people choose their worst enemy, themselves.
