A farmer so loved his cow that he sacrificed her female calf to spare her life during a complicated pregnancy. And whoever (else) would have saved her from perishing would have been justified.
In the second sentence, what must “her” refer to, the cow or her calf?
(note: please do not advise to word the sentence better or correct its structure. I am sincerely interested in surveying the views of those attempting to answer the question GIVEN the way it is. I intend to clarify something for me, perhaps others, regarding possibly a much more significant point. It is also perfectly OK if the responses are ambiguous or the answer cannot be determined. Thank you.)
