In salt to the sea who is the static character?

In "Salt to the Sea" by Ruta Sepetys, the character who can be considered static is Alfred. Throughout the novel, he remains largely unchanged in his beliefs and motivations, embodying the ideals of the Nazi regime and displaying a self-serving, delusional attitude. His perspective contrasts sharply with the dynamic growth and development of the other characters, who face harrowing experiences that challenge and transform them.
