The argument can go this way. Here was a woman comfortably buying wholesome refrigerated, nourishing foodstuffs in ample supply for herself and her family. But in Hyderabad, India, there was another woman starving to death. Maybe, because this wife and mother blithely bought her own ample supplies, while millions did not have half so much, she should be accounted a corrupted sinner. She obviously is part of a system that appears to some people to be sinful.
Sin is supposed to explain the inequalities and the tragic differences.
See the Verkuyl book previously mentioned. This woman who is buying her foodstuffs will have to be judged a sinner in having bought this food, or in being a nonsinner in regard to her purchases. It appears unreasonable to consider her to have been a grievous sinner when she bought her fine and ample groceries while others were starving or were malnourished elsewhere. She should however not be exonerated with some favoritism toward her, nor with careless indifference to the plight of others. But nevertheless, in common sense, she should be exonerated.
