They NEVER died for people to "behave" in immoral ways for they clearly believed in God and the Ten Commandments (see Declaration and Federalist papers). In fact, God was mentioned quite often and prayers were said in their meetings. They would have definately denounced (and did) despicable behavior that spread disease and death and infections to infants. What would be the purpose of permitting such degrading, nihilistic behavior in a productive society?
