if it differs in meaning i can understand that similar to the nazi's taking the swastika from other cultures thus changing it's meaning however the haitian for example could know the meaning behind what's on the sword altered it for purely aesthetics value and using it the same way we don't know enough about why the haitian who i believe is the only one that has the symbol intentionally has the necklace to make the assumption that it's a different meaning once we know why the haitian has it then we can make those comparisons
