The Monsters Are Due on Maple Street Theme: Dangerous thoughts can take control.
This particular scene of which Charlie shoots Peter Van Horton because of his thought based on fear supports the theme of dangerous thoughts can take control. In Act 2, I believe, someone is walking in the darkness coming closer and closer to them, Steve had a shot gun in his hand and after a while when the strange person was approaching Charlie got scared and the thought of someone that was probably dangerous took over his body and he snatched the shot gun out of Steve’s hand. Him and Steve were arguing about not shooting the creature. Suddenly the character comes in closer and Charlie just shot him. As the character hit the floor everybody came near realizing that Charlie shot Peter Van Horton. After realizing who he shot he started defending himself saying stuff like,”Come on Steve you know it was dark I didn’t know who it was. I just got scared.” Everybody started accusing him of shooting so quickly and were suggesting that he were the creature that was doing all of this stuff. It seems as though when he shot Pete Van Horn he started acting worried knowing with a mistake like that the people from Maple Street would have never forgive him and they would always be suspicious. If anything idiosyncrasy would happen he would definitely be the scapegoat.
Charlie took the shot gun out of Steve's hand and accidentally killed Peter Van Horton because he thought he was dangerous.
The characters thought Tommy was dangerous because he brought up the alien invasion and knew all about what was going to happen.
The characters also thought Les Goodman was dangerous because his car mysteriously turned on by itself with no one near it.
