Makes some things a bit clearer...

"Good people will do good things, and bad people will do bad things. But for good people to do bad things—that takes religion."

~ Steven Weinberg

To which Freeman Dyson adds:

"Weinberg's statement is true as far as it goes, but it is not the whole truth. To make it the whole truth, we must add an additional clause: 'And for bad people to do good things—that takes religion.'

" The main point of Christianity is that it is a religion for sinners. Jesus made that very clear. When the Pharisees asked his disciples, "Why eateth your Master with publicans and sinners?" he said, "I come to call not the righteous but sinners to repentance."

Only a small fraction of sinners repent and do good things, but only a small fraction of good people are led by their religion to do bad things.
