Morality is a base human behaviour and does not require much definition. Time and again we see the same basic more appearing, transcending cultures and continuing to exist despite religion.
"Don't be a dick and help each other" just about covers it.
On a global scale, where we fall down is in supporting the "least bad" option when that option remains repugnant (e.g. supporting Saddam back in the day) or meddling for purely selfish reasons (e.g. executing/overthrowing democratically elected leaders simply because they disagree with us).
As individuals, humans are generally great and get along quite happily. As nations we are violent bullies hell-bent on nicking everyone else's sweeties. And IMHO this is because it's the socio-paths who float to the top, becoming business and political leaders.
