Do you honestly think there is no need to regard anyone else in a world without God? If I killed my neighbour's husband so I can have my wicked way with her, would I be punished? Very likely - there are very real authorities who enforce social desires (I don't want to be murdered or my SO raped so I am happy to work to pay for the enforcement of a social contract of mutual protection). Other animals have crime and punishment for breaking certain rules (exile, or exclusion from the mutual protection of others is a common punishment as is violence) is it because they are God fearing? Why should it be?
There's a podcast out there, a recording of a live radio show that had invited Richard Dawkins, in which a (Christian) caller plain simply states - on the air - that God watching him and possibly punishing him was the main reason for him NOT murdering/raping his neighbor.
I swear it, the guy was dead serious! Dawkins and the host were totally baffled (and so was anyone listening, I bet, lol).
