It's been stated by some non-theists that if there was no religion and people knew that they only had one shot at this thing called life, then would people so willingly "sacrifice" themselves, in acts such as terrorism like 9/11? Well, to play devil's advocate for a moment, if we flip this around, one can ask that if there was no religion, then would people willingly sacrifice themselves to go into burning buildings and save a person? Or would law enforcement go into a situation in which there was risk to their own lives? Not only would this risk be to the firefighters and peacekeepers, but their risk could have an impact on their families as well. Does religion give a necessary and beneficial ignorance to society?
