What do monsters and heroes have to do with an author's or artist's outlook

Monsters and heroes can be depicted in numerous ways depending on an artist or author's outlook on life. If an author had been bullied deeply as a child, they may have a lot more demons they're trying to run from. They may draw more monsters than heroes, and may have more designs and thoughts about them. If someone, for example, had beaten bullying as a child, they may create more things where an unlikely hero saves the day because they have been given hope after they were able to tackle their own fights. A person in general's outlook on life means that they will tell a story differently. A generally pessimistic person with a negative outlook on life may not believe in the creation of stories or art where there is a hero who always wins. They may believe that there are monsters too powerful or numerous for that. Similarly, an overly positive person might want to create an all-powerful hero that has been righteous since they were born. Their hero may find fighting monsters easy. Some might not even want there to be any monsters at all depending on how they feel or see things.
