The last, but not least example of why mass hysteria takes over this town is when at the end of act two John Proctor said, “We are what we always were in Salem, but now the little crazy children are jangling the keys of the kingdom, and common vengeance writes the law!” this quote shows that most of the things that are happening are because of vengeance, people are accusing people that no one likes in town in order to become powerful in the town, or to get rid of that people. Mass hysteria conducts people to believe that all people that is being accused are witches without even proving it or listening to what they say in their defense. for this reason hysteria caused the death of many innocent people, just because they were unfairly accused
