The soul, suffering, healing, learning, and spirituality [Night Shift split]

There is also the reverse of that. For long periods of time people were led to believe that lovers having sex outside marriage were committing a mortal sin. Things like dating and just moving on, consensual sexual variations etc were considered too awful even to discuss. This is still true in many societies.

I'm not sure about this, at least if we contrast the central feeling of Love that seems like a powerful key to a lot of Survival-related phenomena vs the hunger for power and control we see across religions (including supposedly secular religions).

This isn't to say there aren't complicated situations where good people can disagree, just that I think we can sometimes just see Evil and recognize it as such. As for these varied societies and their mores, we might look at who is the victim and who is writing the moral codes - men seeking dominance over women, the upper caste exploiting the lower castes, the wealthy who judge the poor, etc...
