I mean, is it the dream of Atheists to exist in a world where people have no moral code or higher being that they look up to? Most humans are depraved and wicked naturally I believe. If you look on various godless societies like the ancient Roman empire, their way of life was replete will all kinds of heinous and evil behaviours that would make and decent man shudder. From homosexuality, murder, pedofilia, to beastiality it was all fair game and apart of everyday culture.
More modern examples can be seen in the societies of the Soviet Union, Nazi Germany, China. Each of the aformentioned countries were well known godless societies that have numerous examples of outrageous atrocities and human rights violations.
No as to which God is best, that is somethign I cant answer. But it can't be coincidental that societies that have a general basis in religion tend to be more stable and long lasting.
Other people already pointed out the historical errors here, but just to add, there is absolutely no correlation between "godlessness" and "evil," seeing as most societies throughout history, good or bad, civilized or barbaric, have been religious.
Also, in no way were pedophilia and bestiality allowed in ancient Rome.
