I'm simply defining civilisation as a society which has developed complex social interactions and which has settled in cities. There's no east and west involved. And defining Mankind by its worst excesses is no more helpful than defining it by its best. Everyday folk were not involved in the Inquisition, nor A-Bomb development, nor the genocide of the Jews. And yes, the Roman and British Empires were built along the lines of creating a better society. You can argue with the validity of that view, but I think you'd be hard pressed to find an individual within those social structures who had the intent of deliberately doing evil. Society, by its very nature, cannot exist unless the many are striving towards a common goal: all else is anarchy. And as the history of human civilisation is a history of precisely that, civilisation, I reject the notion that humans are inherently selfish and self-serving. Maybe I'm an optimist, but I'd rather be that than the alternative.
