Well, the world I'm from, we give people chances to change. It doesn't always take, but everyone makes mistakes. They should get a chance to do better.
Superhero heroes usually have some sort of power that normal people don't. Like super strength or flight or telekinesis. I have a friend who makes star-shaped portals that can take you anywhere in the multiverse. I don't have any powers, except my awesomely amazing abilities when it comes to archery.
