Not sure if you are addressing this comment to me and my Wikipedia post, or at wbl (who I was responding to).
I am not sure what measure anyone would use to compare war crimes etc., but if you are talking about pure body count, then the number of civilians killed during (a) the Rape of Nanking and (b) the Hiroshima/Nagasaki atomic bombs run about the same...
The ongoing firebombing campaign against Japanese cities also killed more.
The bombing raids against Tokyo alone almost certainly killed far more than Hiroshima throughout the war.
And it included the most destructive single bombing raid of the entire war. Operation Meetinghouse [1] burned a quarter of Tokyo to the ground in a single night, and may have killed as many as 100,000 - more than is believed to have died in the immediate aftermath of Hiroshima (though possibly fewer than the total Hiroshima death toll, depending on which estimates are right).
