John Proctor -
ATTITUDE TOWARDS OTHERS: John's attitude toward Parris is that Parris preaches more about hell and sin than God, and we can assume the aspects John misses include God's characteristics of grace and love. This contempt for Parris reaches to Putnam as well who politicizes and uses the church's rules to help himself obtain land or whatever he wants. Putnam influenced his daughter to say she was witched by certain people. John can see through this and doesn't like it because John is a proud and just man.
HOW OTHERS FEEL ABOUT HIM: Society at large seems to respect John as both a God-fearing man and a healthy contributor to a positive society, but there is a faction (Parris and Putnam) willing to poke around and find his flaws and use them to their benefit.
RELATIONSHIP WITH ABIGAIL: By the time the story starts, we know John and Abigail had an inappropriate relationship. We also know John does not want to go back there. Thus, throughout the text, John is presented as trying to run from this while Abigail tries to use it to manipulate him. He will not be manipulated, and this is his downfall or triumph as a character.
RELATIONSHIP WITH ELIZABETH: It is obvious John and Elizabeth have had to work through the fact that their marriage turned cold. Elizabeth and John grow throughout the text as she confesses the cold house she kept and his confession of sin is obvious through his actions. The two work together in discussion through the last acts to help John find his soul. Elizabeth knows John will sacrifice his life, but not his reputation and he dies free from guilt, a major accomplishment for a Puritan.
