It only takes that one person to do the right thing to get others to follow their example. History dictates this. It still happens today. Not all of it makes the media so I guess unless you're in a situation where something terrible has happened, you won't see the good that people can and will do.
A few examples from the media: the relief teams that have pitched up to help in the aftermath of the tsunamis in Haiti/Japan.
The terrorist who killed an (ex?) soldier in broad daylight in London - people who risked their own safety to try and help the victim. And the lady who told the nutcase if he was to bring a war, he was going to lose, and I'm fairly sure most people at the scene would have backed her up on that claim.
