You edited your reply ;). Replying to the first edit, You mean that The Flood took longer to kill everyone who wasn't on The Ark?
And to your second edits meaning: I also like to stick to facts, but I was replying to Christians claiming that non-godly people are more evil than godly people by pointing out how nasty they believe God to be.
Ww2 killed 60-80m and that was caused by Hitler who was Catholic (although he didn't kill in the name of religion).
Of course other things God supposedly created have killed far more, such as Spanish Flu which killed 500m and The Black Death which killed 30-60% of everyone in Europe.
