To humans and other lifeforms on Earth, death was inevitable. Human bodies had too many flaws and impurities in such a way that even if they kept themselves at the utmost pure state of their health, they would still face death.
Of course, one should not forget that there were countless ways people died out there, it was just that natural death is the only thing that all the lifeforms should aspire because freedom is not always everywhere, everything and to everyone. One should accept this life where we are limited, yes, even if one owned the entire world, they could not be the rulers of themselves, they ought to have something within them that they feared so much.
