Jonathan and Martha Kent Dead By Time Clark Becomes Superman?

[MikeandRaph87]

Originally Ma and Pa Kent are elderly and pass away by the time Clark is a young adult out of college. Superman (1978 ) notably changed it do Jonathan dies when Clark is in high school while Martha lives on. Notably the other media follows up on this having Jonathan alone die while Clark is in high school in both Smallville and the current DCEU. After Crisis on Infinite Earths despite darker times in comics (aside from JLI which itself still had dark moments) both Jonathan and Martha survive and adopted Clark when they were around 40 and the DCAU followed this. Superman meant to be lighter character, while his birth parents die with Krypton should his adoptive parents live to old age while Superman is active? Should just Martha live? Should his adoptive parents live on through his time as Superman? In my opinion, I believe both Jonathan and Martha should live through Clark's time as Superman and his adoptive parents highlight the brightness Superman projects to the darkness of Batman's world which core part of his character. Even Superman needs his parents in adulthood just as we do from time to time.
