In "Find the Bad Guy," Jeffrey Eugenides explores the dynamics of arguments within a marriage, emphasizing that couples often feel compelled to identify a 'bad guy' during disputes. When partners focus on winning, they become entrenched in a cycle of blame over trivial matters, such as household chores or personal habits. This competitive mindset can lead to an unhealthy relationship where one person’s victory results in the other’s loss, creating resentment and emotional distance.

Eugenides argues that a fundamental shift in perspective is necessary for marital harmony. Rather than seeking to defeat one another in arguments, couples should recognize that there is no true adversary. The essence of a healthy relationship lies in collaboration and understanding, as winning an argument ultimately harms both partners. By eliminating the "bad guy" mentality, couples can foster a more supportive environment conducive to resolving conflicts and nurturing their bond.
