At the end of act 4 in The Crucible,how does Elizabeth show John that she understands him?

In a setting where so few demonstrate moral transcendence,
Elizabeth's displays in Act IV, scene ii reflect how she has ascended to a new realm of
ethics and understanding.  She recognizes John's dilemma of choosing a compromised life
or maintaining personal integrity even in the face of death.  She recognizes that John's
beliefs and commitment are important elements that help to define individual
consciousness.  Elizabeth becomes the supportive wife embodied with her support of
John.  When her husband struggles with what to do, she does not give an easy or
simplistic answer nor does she answer with her own benefit in mind, as so many in Salem
have done.  Rather, she tells him that he needs to make this decision with what he
considers to be right.  When she says, “whatever you will do, it is a good man does it,"
a moment in which Elizabeth has become the wife who understands her husband in an
agonizing moment of pain and decision.  She has changed and, as a result, the
relationship between both husband and wife is the strongest while death is a reality
that both will face as a restul of this strength.
