Answer and explanation:
I believe that each culture has its rules within its communities. Obviously, a person belonging to a particular culture will think with strong conviction that what they do is right and that no one can overwhelm those beliefs and customs. However, unless they live in a country where there is free will, in the rest of the world there are laws that protect citizens and must be followed and respected beyond all culture. If the practices of a community inflict damage on another individual, I particularly think it is wrong. So in this case I would grant the reason to subject B.
The tone is most likely hopeful, but I could be wrong.
