People of one culture tend to have the same morality because parents pass their morality down to their children and morality is more based around society than it is anything else. Consider that morality is quite different between regions. All you have to do is look at the middle east versus western values. You can see that both do not have similar systems of morality. They might share some concepts, though to what degree varies. For example killing someone is wrong by most moral systems. However many systems include exceptions. Some are fine with the death penalty, while others aren't.
We learn our morality from our parents and our peers. That's why morality changes over time. It's like a great big Katamari rolling up what it comes in contact with. It's why Christians two hundred years ago were pro-slavery, but Christians today generally aren't.
And the bible most definitely makes women out to be property, and non-virgin women out to be worthless (A woman who is not a virgin on her wedding night is to be stoned). And Yahweh's nature is most definitely psychotic. His nature is to kill. People are acting up? Time to flood the earth. David took a census? the blood of 70,000 men will be all that satisfies him. Harden Pharaoh's heart so he won't let Moses's people go, and then when he doesn't let Moses's people go he takes all the first borns of Egypt. All of this is considered "Righteous" by his nature. He had bears kill 42 youths for them making fun of a prophet's bald head. He killed Lot's wife just for looking back.
