I think that what Lincoln was doing at the end of war was a very, very smart thing. And it is maybe one of the great tragedies of American history that people didn’t take him literally after he was murdered. The inability to forgive and to reconcile with the South in a really decent and humane way, without any question, was one of the causes of the kind of resentment and perpetuation of alienation and bitterness that led to the quote-unquote ‘noble cause,’ and the rise of the Klan and Southern self-protection societies.
The abuse of the South after they were defeated was a catastrophe, and helped lead to just unimaginable, untellable human suffering. So had Lincoln not been murdered, and had he really been able to guide Reconstruction, I think there’s a good reason to believe that he would have acted on those principles, because he meant them. We know that he meant them literally, because he told [Ulysses S.] Grant to behave accordingly.
