First,a hero must be brave. When he sees someone do a bad deed, he must be brave enough to catch him or to stop him. Secondly, he must be strong enough, otherwise he himself will be beaten to death. There are fewer heroes now because of several reasons. I think the most important reason is that people don't want to mind other people's business. Because they think it will do them no good. But I think society calls for heroes. Fighting against crimes is not just the job of the police. It's the duty of every citizen.
