For Death and Ending, how about Persona 3?
The overall theme of the game is "memento mori," which is Latin for "Remember you will die."
There are a variety of things that allude to this. For example:
When the Dark Hour approaches, people change into coffins. This protects them from the shadows that lurk during this hour, but if someone has not changed into a coffin and has no means to protect themselves, then the shadows will attack them.
We have a robot who's character arc focuses on her learning what it means to be human and alive.
The mythological stories of Nyx and Erebus play a major part. If humanity truly wishes for death, Erebus will manifest and begin searching for Nyx, and should the two meet then the world is doomed. The entire purpose of the main character is to sacrifice himself in order to seal Nyx away from ever coming into contact with Erebus. And the "memento mori" theme comes full circle.
