You send yourself to hell! - God The Ultimate Judge

[Esquilax]

We have been told we are only responsible for what we have been given. For those who have the full knowledge of God we are expected to respond in kind. For those who have partial knowledge that is what they are responsible for.

If you actually believe this, the most moral thing you could possibly do is never talk about god again, and get all your theist friends do to exactly the same. Dismantle the churches, destroy all the iconography, get rid of every bible you can, and erase every trace of the church on earth, because though you can't save yourselves or most anyone else currently alive, you can certainly reduce the risk of them ending up in hell, and assuring actual moral judgment based on deed and not belief in future, just by making sure you aren't responsible for propagating more knowledge of god.
