Passion, or Obsession?

One of the socratic seminar questions for the novel The Awakening really stuck out to me. Question number 11 says that in 1899 a reviewer of the novel wrote that the novel illustrates, "what an ugly, cruel, loathsome monster passion can be." After reading this quote a few times, I tried to relate it to Edna in the novel. Edna was passionate about finding out what she really wanted in life after experiencing her awakening, but I believe that it was not passion which caused Edna to take her own life. I dont think that passion is the right word to describe it. I dont think people who are passionate about something commit suicide because of it, or commit other negative acts. I think that a better word to fit in this quote is obsession. Edna was obsessed in trying to find out what she was missing, and when she believed that she could never find what she was missing, her obsession caused her to go over the edge and believe that she could not live that way any longer. In real life, whenever I think of people who commit unthinkable crimes, I wonder what caused them to go over the edge. In a movie I watched once (I cant remember the title), there was a husband who killed his wife because she didnt love him anymore and wanted to see other people. The husband was so upset that he killed her, because if he couldnt have her, than no one could. It is later revealed that the husband was obsessed with his wife, and his obsession over her lead him to kill her. This is the example that I thought of after reading the quote and thinking about Edna. I think Edna at first was driven by passion, but it soon turned into obsession because she felt she could not live with herself unless she found what her life was missing. So regarding this quote, I do not agree that passion can be a monster or cruel or loathsome, I think that obsession is the monstrous, cruel, and loathsome quality which controls people's lives and allows them to commit negative acts.
