After reading many articles, I found an article that gave me two different answers to my question. "The Scarlet Letter by Nathaniel Hawthorne: The Effects of Sin on the Mind, Body, and Soul," by Nicole Smith wrote an article that helped me understand the answer to my question. The article explains how humans naturally think of how another person views them. People care about the way they are viewed because they want it to be positive. Hester or Dimmesdale possibly thought that the other would no longer love them if they did not show affection to each other. This, potentially, could have pushed them to making an unwise decision.
