If you really want some scary rationalize eschatological thinking, try "The End of the World: The Science and Ethics of Human Extinction". The book describes the Doomsday Argument which basically states "we're a young species and odds are we're going to off ourselves." Surprisingly, the argument grounds itself in Bayesian reasoning and has been stubbornly immune to attempts to invalidate its methodology, premise, or conclusion.
