the problem with religion is that no one has actually met these supposed deity's or been to heaven after death. Or if they have it's long enough ago to be questioned and there's noway for someone to prove being there. if all suffering was ended then wouldn't that remove one side of the coin. isn't choice what makes us humans the ability to choose. plus whats to say that once you get to heaven you cant get booted out. in the end religion cant make us better or worse people, only we can. that said religious zeal still exists and they are the poeple who tend to do the most damage. but those extremists groups could just as easily be unreligious as religious. if you get a child and teach it it's okay to rape murder and kill. It will be no different if they believe in god or not, they will still kill. Religious beliefs is only so widely promenant in extremist groups becuase it gives them something to justify there actions. It also means that they are a lot harder to turn and more zealous in what they do. becuase if your a suicide bomber and you belive your doing it for something greater then youself then your more inclined to do it. Where is if you are doing it becuase you believe its right your more inclined to chicken out. All major things that have happened in history have had a cuase behind them. All the revolutions have had a cuase behind them generally for a better life. the crusades happened becuase they where conquesting for god they believed he wanted them to. this is the same with poeple that we generally asociate with some religions.
