The same is probably also the case for most superhero comics. They are made for teenage boys going through puberty. Boys with a changing body that now is much stronger than the younger kids. The stories try to give guidance: You have to restrain your new power and use it for good. Some aspects of your transformation you should keep to yourself. There are other kids undergoing these changes too who use it to bully their weaker peers. Those are the bad guys. There are also bad girls who abuse their new powers (which are not defined by muscle strength) to entice and manipulate other people.
