We humans are a very interesting specie. As groups we tend to destroy everything around us, we hurt and kill our own for the sake of power and wealth, we turn beautiful natural sights into dirty cities, factories, and other stuff... But as individuals we are capable of love, doing good, having faith and hope, help the ones who need it and do wonderful things for the world. Why is it that the collective mind is so destructive? Are our leaders evil? Are we, as groups, run by fear and hate? I don't get it.
Any thoughts?
