Evidence 1: "He always was an odd ball. Him and his whole family. Real odd"
Evidence 2: "You killed him Charlie, you shot him dead"
Evidence 3:" They pick the most dangerous enemy that they can find.....and it's themselves. And all we need to do is sit back and watch."
The theme of "The monsters are due on Maple street" is Mankind is it's own worst enemy. The first evidence that supports the theme is the scene in which Charlie calls Les and his family an oddball. This supports the theme because they are friends and now Charlie is acting like Les is his enemy and is not human. This proves that Charlie will do anything to prove that someone really is an alien. He is putting everyone against each other. The second evidence is the scene where Charlie shot Pete Vanhorne. This scene supports the theme because Charlie shot his own friend because of what he assumed. he let his imagination get the best of him and made him think the worst about his own friends and neighbors. He let himself blame everyone for something they didn't do. The last evidence is the scene where the aliens are talking about the humans and how they create their own problems . This supports the theme because they are saying that humans go to the most vulnerable person and picks the to be a scapegoat. They are right because that is exactly what Charlie and the other neighbors did to the people that they thought were aliens. This shows that people will create problems that aren't even there. This is why the theme is "Man kind is it's own worst enemy.
