I voted no. Without religion the world would be only scientific. The religion would essentially be science. There would be no real reason to be a good person, because in most religions people believe that being a good person will get you good things. If there is no reason to live, nothing after life to live for than people would be overall really depressed. Of course religious wars happen all the time. What about WW1 and WW2? You may say World War 2 was started because Hitler hated Jewish people, a religion. You have to remember though, he killed alot of people based on culture and appearance, not just religion. That war probably still would have occured even without religion. So you have to see how religion puts meaning in alot of people's lives and is overall a great thing.
