Evidence 1: Everyone is blaming Les Goodman for turning off the power.
Theme: Mankind is its own worst enemy.
Ya Les, explain yourself this instant!
This is absolute nonsense!
Evidence 2: Charlie thought Pete Van Horn was a monster so he shot him.
Evidence 3: The residents all started to argue again.
In the first scene, it shows that the people are turning their backs on Les Goodman. They are blaming him which shows an unwise act. Also, they are blaming him for something he didn't even do! On the second scene, it shows that Charlie was so worried that he shot Pete Van Horn thinking he was the monster that has been messing with them. It also shows how Charlie didn't think twice about his decision. He could've waited until Pete Van Horn was visible so he wouldn't have shot him. On the third and final scene, it shows that they are using violence to try and solve the problem. For example, people were throwing stuff at the windows which is an act of violence. They could've just solved the issue quietly and calmly.
