Haha, this 18th century lyrics! You cannot steal a person from another. A person is not the possession of another person not is a person the property of a thief post factum. The whole idea is sad. The culture of simply owning a person as a slave, be it spouse or servant, crofter or warrior, comes through. How close you might feel any sort of attachment doesn't make you an owner. It might make you rather feel obsessed than owning.
