What is a hero?

The definition of hero is an illustrious man, supposed to be exalted, after death, to a place among the gods; a demigod, as Hercules. Well, I think that is correct but not totally. I think heros are the people who are willing to save or sacrafice for the other people without any benefit from him or herself. They will all share the quality of courage, honesty, selflessness, and determination. I think the most important charateristic of being a hero are courage and selfessness. Hero needs to have the courage to fight for the others. Like when you see a little poor puppy got chased by a crowd wild furious dogs, you need courage. When you see a person is cheating on test, you need courage to charge him. Hero shouldn't be selfish, otherwise that will be like a jerk, that is like hire somebody to do some specific job for him. We don't call that hero. Harriet Tubman is a great example for hero. He ran back to save the slave even though he was already free. He got the courage to help the slaves, and he is selfessness. He fought justice for the slaves, and that is a hero. Hero is actually not that hard to be. Just remember that don't do bad things to the other people, and try to help the people that needs help. That is what I think!
