Do we still need Heroes?

I feel that we still need heroes. In the world, war and riots are still occurring and many people have lost their lives. We need heroes to help solve our problems and make the world a peaceful and better place. Theft and murder are still rampant on the streets. Riots and wars are still occurring. Lastly, heroes are righteous, thus they would be able to set a good example to us. The world still needs heroes to help us keep the world safe.
