Do Atheists hope there is no God? TL;DR: upon close inspection of the biblical god, it quickly becomes apparent it was fashioned after Man's lesser-desirable traits, making the worship thereof foolish at best.
I was raised to be a christian, dragged to more than a few churches. Eventually, as a teenager, I got bored enough to actually read the bible, not selectively, but cover to cover. It was interesting, so much so that I was compelled to concurrently read multiple versions/iterations of the bible, so as to compare and contrast the language used, with the hope of gleaning a more accurate understanding.
Being full of teenage hormones and a strong natural sense of justice/fairness, I was more than taken aback by the plethora of blatant contradictions I found in the bible, not to mention the horrific behavior of the main and ancillary characters. I knew there were some in there (contradictions) , I'd encountered a few previously, but in my quest to better comprehend the literary work and thus the derivative ideologies, I had gone about it with as open and objective a mind as I could manage. Suffice it to say that the end result was my complete and total atheism, at least in regard to the Abrahamic/biblical "god".
It wasn't merely the contradictions, the imperfect nature of what should've been the perfect work of a perfect entity, that drove me so far from belief, but more so the childish and disgusting, outright repulsive personality of this god thing.
Do I hope that your terrible magic sky daddy doesn't exist? Obviously, but not actively or often, I so very rarely to never think about it. If you've actually read the bible, in its entirety, in as short a period of time as you can manage, you would be insane to wish for such an entity to have any basis in reality, unless of course, you were some sort of immoral masochistic sociopath.
