What is a good thematic statement (universal theme) of the message/lesson the author of The Crucible conveys?

I would use some language that helps convey aspects of
those themes as well. For example, the use of guilt and manipulation play into those
topics as well.

1. Authority figures within Arthur Miller's
The Crucible allowed their hopes of maintaining great power
interfere with their care for humanity, the purpose of the very offices to which they
were appointed.

2. Fear manipulated the town of Salem
during Arthur Miller's The Crucible causing a mania that cost
people their very lives.

Are you writing a thesis statement
in two sentences? What is the purpose of your assignment?
