What about evil done in the name of God?

Atrocities in the name of Christ are inconsistent with real Christianity (that is, following Christ).
Atrocities in the name of atheism are consistent with it. 
Because if there is no god, then there is no absolute right or wrong. 
If we are merely evolved collections of purposeless atoms, then do whatever feels good, because YOLO, right?
This is why more than 120,000,000 people were slaughtered by atheist regimes within the last 100 years. 
Source of that last stat:

Also at that link, you'll find that about 14,000,000 people have been killed in all religion-oriented wars, persecutions, etc in all of world history. So all of the people who have been killed by atheism in one century total 8.57 times more than those killed by all religions in all of human history. Hmmm...I thought Dawkins said religion is bad for humanity, & atheism is good? 

Of course there are atheists with decent morals. But they learned those morals from Judeo-Christian influence on society.
