The irony there was that the blacks were more Christian than the whites, who were better off here than in Europe, and who ended up suffering for their own good for a hundred years after slavery.

It was Jefferson's wolf by the ears, and why that was a problem - you had to admit it was a wolf.
I don't know how far you can fault someone for following the mores of their class - and the South was really evolving a regular feudal system like the one their ancestors left - but when it's clear they know better it's a little harder to let them off the hook. Lincoln spit it out - it's not so much good for you to be a slave but good for me you're a slave! Translated for Lee: the old man says in his will you're free but, doggone it, it also said I had to get the place out of debt and I can't afford to pay anybody anything...sorry, you'll have to wait! But if you think Lee had problems with slavery, you ought to have heard his wife who had no problem whatsoever. Free them? You don't leave puppies out in the woods, do you? They'd be just fine if those abolitionists would quit riling them up! (Blacks don't have a single thought in their heads until a white puts one there...

)
I sometimes wonder at this problem Lee had about hanging onto Jefferson's wolf and rationalizing the 'peculiar institution' then finally tossing the ball to God - your call, I don't know! Someone like Forrest didn't worry about it and didn't have a wolf by the ears. It's legal, it's where the money is, you do this and I'll do that - business is business. He didn't drag God into it! However, he didn't have generations of families that had been owned by generations of his family. I think that close, very long term relationship had a lot to do with Lee's conflict about slaves.
