Superman endures because he represents an ideal that is both impossibly grand and profoundly human — a figure who carries limitless power yet is defined entirely by restraint, empathy, and the quiet belief that people are worth saving even at their worst. Unlike darker antiheroes or morally ambiguous protagonists, Superman’s conflict isn’t whether he can save the world, but how to remain gentle in a world that keeps demanding hardness. His strength lies not in flight or force, but in conviction.
