What is the core difference in the philosophical approach to heroism presented by Marvel and DC?

Marvel heroes often grapple with the burden of their powers and the sacrifices they must make, emphasizing the human cost of heroism. DC heroes frequently embody ideals of justice, morality, and selflessness, representing a more aspirational and almost mythic concept of heroism. Marvel leans into the 'everyman' hero, while DC leans into the 'champion'.
