Atheists: What would you say to a dying child who asks you if they'll go to heaven?

[Mister Agenda]

There's a big difference between thinking you ought not to have children and telling other people they ought not to have children because you don't like what you imagine about them

that's probably true(though not everyone agrees) but I still think that responcible atheist parents should ask their children occasionally if they like being born into godless purely material world.

Well, the most likely explanation for that is that you're an asshole, Dmitry.
