The vast majority of People are good yes. The main problem is that most people stop caring too quickly. On a multidimensional empathetic scale they stop caring with a nigh exponential drop off the further away from the this and now the other person is. Once someone's genetic and then phenotypic expression is far away from theirs, once the spacial, chronological and cultural locations etc. are diverged; people stop caring enough. Sometimes the person that they do not care about is their future self.
The keyword is enough. Certainly if everyone was too empathetic that would neither be good. But I do think the world would be a better place if more people did not set the line of when to stop caring and empathizing so close to Now and Me. If they picked a slightly less steep atttenuation function then we would not have so many perfectly good people that were bigoted Xist bastards when it came to topic X. or peopele who were just following orders. or just having a bit of fun. or well at least it is not me. or on and on. for example.
