I would have followed the plan Lincoln outlined in his Final Speech and was willing to extend to Louisiana and Tennessee.
I totally agree with you. If America had followed through with Lincoln's ideas after his assassination, then there wouldn't have been so much resentment and the birth of the KKK.
Also a lot of people in the civil war in the south were not just solely fighting for the right for slavery. Some, like Lee, were fighting because it was their home. Though, if you read the constitution of the Confederates... it kinda points out it was over slavery. But it doesn't mean the leaders were evil, they simply loved their states.
