Can Heros still exist?

With the world so blinded and cynical today with so much falsehoods and ignorance, is it possible for a true hero to exist in our society? If there is truly a hero out there, would they want to rise up to help this society that will greet him/her with nothing but indifference, hate, or fear?

Humans today would not give the benefit of the doubt, in fact it would be the opposite. They would face this hero with everything that is bad and ugly about humans. The hardest fight this hero would have is with the very people he/she is trying to save.

Why would the hero bother?

I hope I am wrong and that people are better than what I give them credit for.
