What is a hero?

A real life hero is someone who fights for what they believe is right. They speak their mind and tell their world their opinion. I'm sure they have a second thought on critizisim and side comments from the people, but a real hero would do it for those who have the same thought and agree with what they are spreading across nations, "critizisim" is just a word that they pay close attention to if needed, but it ussually isn't something they care for. They just want to grab the attention of the people and show that they are trying to make a difference in the world or country. A real hero makes a difference, even if it's small. They show they care about what is advertised revolving around society and the people. They are hero's.
