How much pain can atheists withstand ?

[The Grand Nudger]

Presuppose hell exists, presuppose god exists, then tell me that good is whatever god does.

God is classically defined as a benevolent being, so...? 

Of course, one can ask why one would suppose God to be benevolent, this is a difficult issue that probably requires an appeal to revelation.

-and whatever benevolent is, is whatever god is doing.  Like drowning bitches or glassing cities.  

 God existing, and hell existing, doesn't make said gods subjective morality objective....lol? 

Subjective, objective are nothing but labels, remember? But sure, if you define subjective morality as any moral system ordained by a subject, then yeah God's commands are subjective by definition. But God, being God, can assess moral facts better than anything else, again, by the very definition of the word God. 

If you don't like the word objective, let's just say that a moral system ordained by God is the best subjective moral system possible, by definition. That's enough, I think.

Correct, terms are labels.  And the label that accurately corresponds to the morality you subscribe to and advocate for..is subjective.  I have absolutely no problem with the term objective, or objective moralities.  I am, myself, a moral objectivist.  You, as a moral subjectivist, are the one with a problem with such terms and labels.  You don't think morality is objective.  You don't think there is such a thing as right or wrong in fact.  You think there are things that gods do, and things they tell us not to do.
