Yes, I do believe hero's are real, now, not the ones that fly around in a red suit, or have incredible strength, but I mean ones that help others when in need. Take firefighters for example. The literally fight frees. Now, what will the world be like without them? There will be fire everywhere and society will die out. Same with police officers. They fight the "bad guys" and arrest them, without them, they would hurt our loved ones. So yes, I do think they exist.
