I’m not sure what the “revelation” is? How is this related to what I said?
Putting that aside, your philosophy sounds shallow. Death is certain, but how long you have to live and the quality of that life are not predefined. An incompetent passenger-pilot trying to save you from a crash will at worst make no difference. But an incompetent doctor can teach you that death isn’t necessarily the worst outcome.
There are many healthy psychological ways to accept the certainty of eventual death. But the process is inevitably painful.
I think the different ways people accept death explains a lot of people's psychology, like how you can guess people's attachment styles or Freudian stage fixation. For instance, billionaires who pour all their money into anti-aging research clearly are not handling it well.
