You want to have some related fun, look up the implications of decision-making and morality if you believe in the multiverse.
I read science fiction and the implications of the multiverse are one issue that writers don’t handle very well. Several writers have ended their careers mired in the mediocrity of trying to reconcile their various “universes” into a multiverse in which they are all real. Asimov tried to do it with the Foundation and Robot stories and the results were cringe-inducing.
But some scientists have written about the morals of living in a multiverse; if you gamble and lose you can be comforted in knowing that somewhere else another eigenyou won.
