Is religion a blight on the world, being a leading cause of genocidal wars? Thus it would appear if you listen to the fervent preaching of the new atheists but it appears that they may not have done their homework.
As a disclaimer, I haven’t read the book in question myself but it doesn’t take a great student of twentieth century dictators to recognise the list of names such as Stalin, Mao and Hitler and to notice that those who actively turn away from the peace of Christ seem to be significantly more dangerous. A salutary lesson perhaps for those who claim that even our most altruistic acts boil down to mere selfishness on behalf of our species.
