Barbara Kay treats Caine as a "Jesus figure" often depicted "kneeling before orphaned or distressed children, and comforting them"; she notes that his marriage to a "victim-figure with leukemia" was immediately and inevitably followed by his wife's murder. Matthew Gilbert notes the many "literary, pop cultural and even biblical associations" of the character's name, and highlights the allusion to the Cain and Abel story, describing Caine as "living in the shadow of his late brother".
