As Steven Weinberg has said:
"With or without religion, you would have good people doing good things and evil people doing evil things. But for good people to do evil things, that takes *religion."Or, as Christopher Hitchens has said:
"Try to think of a good act performed by a person in the name of God or religion that would not have been performed by a non-believer.- - - - -
"Now, try to think of an evil act carried out by a person (or group) solely in the *name of God or religion that would not have been carried out by a non-believer."
*This blogger would expand the terms "religion" or "god" to include any authoritarian, quasi-religious government.
