Sometimes people do say the world be a better place without religion. Because how people take religion too serious , so if you are not of the same religion which they belong they have nothing to do you. Would the world be a better place without religion? Has region not play any role in our society.
Religion is not responsible for the bad state the world is but those bad people who practice the religion. Every religion preach peace and love but it depends on the practitioners to do them or not. We have good and bad Christians, like we have good and bad muslim, good and bad heathens. So it is not a religion thing but people problem. If everyone keeps to the rule of their religion the world will be a better place.
