How does the quote The bravest of individuals is one who obeys his or her conscience apply to Moon Down by John Steinbeck?

In his novel "East of Eden", American author John Steinbeck wrote, **"The bravest of individuals is one who obeys his or her conscience."* While this does express one of the central theme throughout his writing, and many critics link this directly to the characters of Lee and Cathy in "*East of Eden*", this quote does not in any way apply to his novella _ _"Moon Down"_ _.
