Judge not lest ye be judged? These words would prove to be good advice for the characters of The Witch of Blackbird Pond. Everyone is passing judgment on everyone else. The judgment culminates when Kit is put on trial, accused of being a witch. The novel also wants readers to consider the concept of justice – in Kit’s situation, to sure, but also as it relates to the colonists whether it's just for them to be ruled by the distant King of England.
Kit's biggest problem with William Ashby is that he's too judgmental.
Though it is home to some good people, Wethersfield overall is not a just community.
