They left the game....
In time I think we will change our phrasing of "they were killed" or "they died" to they left the game. As the aliens have said we are just "containers" - we contain our consciousness like a radio receiver connects to a signal. No one ever dies - we just leave the game. I think that is the biggest ah ha moment when you die - just a game....ok. No regrets, no worries of players left behind, just... oh ok.
