If so many people think they need theistic fantasies to make life worthwhile, maybe it's not?

Sure, there's those rowdy party animal atheists who love to eat, drink, and use the bathroom, but what about all the rest of the miserable people in the world? Should a miserable person who needs drugs, God, or Tolkien just to make it through the day take it upon themselves to not impose their genetic structure on another sentient being (ie. reproduce), out of compion?
