Roger’s conscience is telling him to no help save the drowning boy and just keep on moving. This decision was most liekely made by his ‘bad side’ of his conscience.
“To be like salt, like a city on a hill and like a light that would light the way for others. His followers were to be a good influence on others and try to get other people to do the right thing”, is one of Jesus’ teachings.
I believe that this teaching will help people with their decisions, especially decisions on which side of our conscience we should follow.
