> With or without religion, good people can behave well and bad people can do evil; but for good people to do evil — that takes religion.

A great physicist without any doubt, but this quote in my opinion is symptomatic of a very shallow analysis when it comes to religion.

Without religion (or some other set of values, even secular values) it’s very difficult to define good or bad. You can come up with some general idea of treating other like you would like to be treated yourself, but the devil is in the details and there’s a ton of details! Also, many bad people did good deeds because of religion.
