There are plenty of people who believe in God, yet are also wicked and mischevious and feel justified in "running rampant" regardless of their belief.if it wasn't for those people who believe in God, the wicked and mischevious people would run rampant.
Predictibly, your answer will be "well those persons are'nt 'true Christians'."
But I totally reject your assertation that religious = moral. It *CAN* be....but so can NON-religions = moral.
"Morality" was first a set of social conventions that even the higher primates observe. Simply put, it is healthy for a society to observe sets of rules that will promote the continuation of that society.
