The Intuition Behind the Argument
Taken from Maverick Philosopher's insightful post Evil As it Appears to Atheists and Theists:
Thus atheism is bred in the bone before it is born in the brain. The atheist feels it in his bones and guts that the universe is godless and that theistic conceptions are so many fairy tales dreamt up for false consolation. This world is just too horrifying to be a divine creation: meaningless unredeemed suffering; ignorance and delusion; the way nature, its claws dripping with blood, feasts on itself; moral evil and injustice -- all bespeak godlessness. There can't be a God of love behind all this horror! For most atheists, theism is not a Jamesian live option. What point, then, in debating them?
This deep intuition of the godlessness of the world is prior to and the force behind arguments from evil. The arguments merely articulate and rationalize the intuition. The counterarguments of theists don't stand a chance in the face of the fundamental, gut-grounded, atheist attitude. No one who strongly FEELS that things are a certain way is likely to be moved by what he will dismiss as so much verbiage, hairsplitting, and intellectualizing.
