You said that perfectly. Except I am sure that more than 100,000 southerners died at the hands of the North. Total deaths is supposed to be +640,000. But I have never heard the number of North and South separately. If it was only 100,000 we were much better shots than the Union army was.
I was only using battlefield deaths so the "Lincoln was a God" crowd would not accuse me of an oversight.
Traditional total Confederate death toll was 258,000 and Union deaths at 360,000 for a total of 618,000. Traditionally, the battlefield death totals are something like 94,000 Confederates and 108,000 Yankees.
A modern-day
demographer has recently placed total war deaths at 650,000-850,000, splitting the difference to 750,000, or 21% higher than the previous estimates.
Using his estimates, that would increase the Southern battlefield deaths would be somewhere around 113,000, but what's 20,000 deaths when you are talking about the glories of saving northeastern businessmen's profits?
