Arguments for their credibility:
* Mme Loisel's social climbing and desire for luxury are relatable. Many people, particularly in the 19th century, dreamt of a life beyond their means, and Mme Loisel embodies this common aspiration. Her longing for social advancement and her willingness to go to extreme lengths to achieve it are understandable, even if ultimately misguided.
* Her husband's love and devotion are genuine. He sacrifices his own desires and comforts to fulfill her wishes, even though he knows they are beyond their means. His unwavering love for her, even when facing financial hardship, adds depth and complexity to his character.
* Their initial reactions to the loss of the necklace are believable. Panic and fear are natural reactions to such a situation, especially considering the social consequences of losing something so valuable. Their decision to replace the necklace, while ultimately foolish, highlights the power of social pressure and fear of shame.
Arguments against their credibility:
* Mme Loisel's lack of awareness and self-reflection is problematic. Despite her privileged life, she consistently underestimates her situation and allows her vanity to overshadow her judgment. She never acknowledges her own role in the tragedy, blaming her misfortune solely on the loss of the necklace.
* Her husband's passivity and lack of initiative are questionable. While he loves his wife dearly, he allows her to dictate their financial choices and fails to challenge her unrealistic expectations. He lacks the strength and courage to stand up for himself and his own well-being.
* Their actions after losing the necklace are unrealistic. The decision to replace the necklace with a replica, costing them ten years of their lives, seems implausible and exaggerated. Their lack of initiative in contacting the original owner or reporting the loss raises questions about their intelligence and resourcefulness.
Ultimately, the credibility of Mme Loisel and her husband is a matter of interpretation. Some readers may empathize with their struggles and sympathize with their actions, while others may find their choices foolish and their lack of responsibility frustrating. The story invites us to consider the human desire for social status, the consequences of misplaced priorities, and the power of illusion.
While their credibility can be debated, their flaws and weaknesses contribute to the story's enduring power and its exploration of universal themes.
