What are other pieces of literature that are similar to The Crucible in terms of theme? Thanks! :)

There are several themes in The
Crucible, which means there are many stories which could be similar in
theme.  One idea which Arthur Miller develops is that of intolerance for sin, among
other things.  A good comparison piece, then, is The Scarlet
Letter, by Nathaniel Hawthorne.  Both are set in the Puritan world, and both
delineate the consequences of intolerance in all
forms.

Another theme is developed in the character of John
Proctor, a man tormented with inner conflict--a good man who sinned;a man who wants to
tell the truth but knows the consequence will be death; a man who loves his wife but had
a casual affair; a prisoner who can save his life but lose his soul by signing his name
to a lie; and more.  Another work in which the main character suffers inner turmoil is,
of course, The Scarlet Letter.  Arthur Dimmesdale is tormented with
inner conflict--a good man who sinned; a man of God who sinned against God; a father who
must not claim his child, or her mother; a man of truth who is living a lie; a man who
is revered by others but reviles himself; and more. 

Choose
a different theme and you'll certainly find even more works for
comparison.
