E.g. if you die when low on chakra, you'd need chakra to undo that, which you cant (creating a circular loop) thus the jutsu fails. Undoing Rinne Tensei would essentially require a sacrifice of equivalent lifeforce to undo it. Minor injury (like simply being hurt) is undone by chakra, but it seems very doubtful that being hurt by something chakra can't really replace is so easily undone. but didnt madara die while being completly exhausted and empthy?(in his fight with hashi before being edo tensei'ed) he didnt even have the sharingan open right?
