In the novel/cartoon Maus how does Spiegelman's choice of medium lead to a deeper individualized understanding of the life altering effects of death?

Here is more of the excerpt I mentioned before,

Spiegelman also makes the stylistic decision not to idealize anyone or anything, neither visually nor through any of the comic's diction. All of the characters within the same species are approximately the same size, so no single mouse appears more powerful or significant than another. The book does not venerate Vladek for surviving Nazi oppression; instead, Spiegelman examines his character and even occasionally openly criticizes his father. After all, mice are humble creatures---hardly honorable ones.
