I think if you’re having difficulty understanding what they mean by hero, it’s because you’re thinking too concretely, not because people are using the word in an atypical way. I can try to describe the tasks anyway—often they’re someone who uses skills like bravery, leadership and insight to perform difficult and important tasks for society’s benefit. But you can be a hero without meeting those specific criteria. It’s more of an aesthetic.
