Why is John Proctor unwilling to sign the confession? What is the significance of his "name"?

John Proctor refuses to sign a confession that he served
the devil by practicing witchcraft because it is a lie. He has lost everything--his
home, his family, his community--but he refusesd to give up his good name. When
confronted about having committed adultery, he admits it, even though he is confessing
to having sinned. He does so because he knows that he has done wrong and must suffer the
consequences. But when he is asked to sign the false confession just to end the trials
and punishments, he will not do it. He does not want his sons to grow up with a father
who is labeled a liar or who chose the easy way out when so many of his friends and
neighbors have been killed. Having an honorable name means more to him than living under
a lie. When he says that he is "not worth the dust on the feet of them that hang," he
means it. He would rather die with them than live knowing that they died for
nothing.
