So, from the top of my head.
The OT found it OK to pay for rape and even named the sum, owed to the father, not the victim.
Medieval (christian) law makers thought it to be OK to pay for murder and set up different fees, according to the value of the murder victim in question.
Middle American cultures thought it to be OK to sacrifice people to their gods.
Hell, yeah, looks like objective moral standards to me.
