The worst would be trying to live with the personal cognitive dissonance of cursing others out with "Goddamn you" or "Go to hell."
But then, I don't believe in hell (a later Christian concept which postdates Christ and all the surviving apostles) or a corporeal God (you know, a Joe God who lives at One Heaven Place) who could or would damn anyone or anything
and yet I exclude no Christian based curse from my lexicon, either. <shrug>
Nevertheless,
personally, I stand with such luminaries as Big Al Einstein in having a strong and enduring sense of the divine:
"Science without religion is lame. Religion without science is blind."
-- Albert Einstein
And if you don't like it, Goddamn it, you can go to hell.
