Maybe the plot is too confusing or the character development is not good. That could be what's wrong.
In this context, Alfred's character could be developed through his relationships. His relationship with Mad Bruce could be shown as a struggle between his love for Bruce and his concern for Gotham. He might also form new alliances in the fanfic, for example, with other members of the Bat - family or even some of the villains who he realizes can be useful in curbing Bruce's madness. His skills as a strategist and a medic could be enhanced, as he uses them more frequently to deal with Bruce's erratic behavior and the resulting chaos in Gotham.
Another form of punishment could be emotional. Alfred might give Bruce the cold shoulder, refusing to offer his usual words of wisdom or emotional support. This would make Bruce feel isolated and force him to reflect on his actions.
One possible reason could be that Bruce is being too reckless in his Batman activities. Alfred, being the caretaker, might see Bruce endangering himself unnecessarily and decides to punish him to make him more cautious.

One popular theme is friendship. Given his role in the story, many fanfics explore his relationships with other characters in terms of deepening friendships. For example, his bond with Thomas might be further developed in a fanfic.
One reason could be that Bruce is being too reckless in the fanfic. Alfred has always been there to keep Bruce safe and if Bruce is constantly putting himself in unnecessary danger as Batman, Alfred would be disappointed. For instance, if he jumps into a fight without proper preparation or a well - thought - out strategy.
Another possibility is that Bruce is making moral decisions in the fanfic that Alfred doesn't agree with. As Alfred has his own set of values and he has been around Bruce for a long time, if Bruce starts to cross certain ethical lines in the name of justice, Alfred would be disappointed.
