Superman is a person absolved of all human weakness. Unstoppable and invincible, he is free from the insecurities that grip humans, from all the fear and hatred that we use to console ourselves. He is a man who chose to become a superhero because it was the thing that made the most sense - not for any reason, but simply because he was endowed with so much power he could only really choose to protect the world. A person who, ultimately, makes the right choices.
That's Superman.

Respectfully, no it's not.
Clark Kent, Kal-El, Superman, chose to be a superhero because he wanted to help people and do the right thing. Because he saw all that he could do, and was determined to make a difference without enslaving the world to his will. He's a man, a being, who could conquer or crack the planet, but instead chooses to save and protect it on a daily basis, for a population that sometimes idolizes him and sometimes mistrusts him.
Superman is the hero who will divert a flood, save a kitten from a tree, talk a suicidal young woman down from a ledge, and pull people from a burning building all in one day.
He is not perfect; his powers have limits. His mind grows tired. His spirit can bow under the pressures and expectations and all the times he wasn't fast enough or wasn't strong enough.
But yet, he endures. He remains. He stands.
When a being who is the embodiment of tyranny, despair, control, hatred, pride, and every other terrible concept in existence strides to Earth and rains down fire and blood and death, filling the skies with his Parademons and his tanks and his twisted "champions", Superman is one of the first to challenge him. The first to say "no". The first to take those blows that would destroy lesser beings, and drive back Darkseid to the hell-pit he came from.
When a young boy finds himself saddled with powers he barely understands, with no family to support him, Clark Kent stands beside him and offers him help.
Doomed Planet. Desperate Scientists. Last Hope. Kindly Couple.
That is Superman.
That's not all to say that alternate interpretations of Superman should never be made, but that we must always filter them through that very lens:
that they are an alternate interpretation. They are a step away from the source, the core of the story and the character. That's what makes such stories intriguing, if done well, is their exploration of "what if?".
