What a loaded question...boom and a good one to! As a whole it seems religion promotes righteous or right behavior. In the past for decades there has been more systematic and righteous behavior. Looks like that is starting to unravel now. So has Religion, lots of disbelief has set in. However, to borrow a line from the Beatles imagine there's no heaven, or religous people on earth since the beginning of Man. That would produce War not even imagined! Peace has come from those trying to do the right/righteous thing. peace has been a by-product of people doing the right thing! Righteous! Religion! Peace! I also believe one can achieve peace within if one chooses to! Then again, it becomes a quasi Religion in itself within, doesn't it! I'm persuaded to go with the idea of one God, unphathomable love, the mean thing trying to mess it up. That would be the Devil himself and there you have it! Love, Peace & War! Surely there has to be something better than this ole ball to look forward to though... That would be Heaven! And something to avoid Eternal Jail... That would be Hell! Good & Evil! Where does it come from... That's a different question!
