This question is for ‘hero’ in all forms: realistic, fiction, superhero, comic book, anime, etc. Let’s say a person is flawed, or is very arrogant, or has a superiority complex, etc., but also does heroic things—like being a firefighter, doctor, wizard, superhero, whatever. Do you think that person is still a hero despite having negative personality traits?
That will depend on your values and culture. In ancient greece, heroes were warriors that killed many or defeated impossible odds. Now it is usually about self sacrifice or saving many people. Some people see humble hard workers as heroes. Though that also has an element of self sacrifice.
