A Moment of Judgment
"My aim was to create a scene that was perfectly morally ambiguous, and in which the reader might quite justifiably side with either Andrew or Sarah. Andrew isn’t such a bad guy. What he fails to do on the beach is what most people would probably fail to do, myself included. Once Andrew realizes he’s made the wrong choice, it’s too late for him because the moment has passed and he is condemned to spend the rest of his days regretting that he failed life’s test. Sarah is lucky, really. She’s not inherently more moral than her husband, but just at that one critical moment she happened to do the right thing. This means that she can look back on her actions on the beach without too much guilt or shame. She can move on with the rest of her life while Andrew must enter a terminal decline. It’s ironic because Sarah’s infidelity is the reason the couple find themselves on the beach in the first place. And yet her premeditated affair goes unpunished by life, while Andrew’s momentary failure of courage dooms him forever. Life is savagely unfair. It ignores our deep-seated convictions and places a disproportionate emphasis on the decisions we make in split seconds." [My emphasis.]
