"How was I supposed to know?"
"Are you all gone crazy?!?!"
Evidence 1: In this scene Charlie shot Van Horn not knowing who it was because he was scared.
In "The Monsters Are Due on Maple Street" by Rod Serling, one of the main themes is that fear and suspicion can make you do crazy/bad things. One reason is when Charlie saw a dark figure he shot it instantly. He shot it not knowing it was Pete Van Horn because he got scared. Another reason is that everybody started to accuse Charlie of being the "monster". They got suspicious and turned into a mob, which caused them to chase Charlie to his house. Someone threw a rock at his window and he got cut with glass. The last reason is everyone was freaking out and blaming each other for everything that was happening. Steve then shouted hysterically at his neighbors saying "Are you all gone crazy?!?!" and everybody stopped what they were doing. In conclusion, these are a few reasons why one theme of "The Monsters Are Due on Maple Street" is that fear and suspicion can make you do crazy/bad things.
Everybody was suspicious of Charlie because the lights in his house turned on.
Steve shouts at his hysterical neighbors because they're turning into a mob.
