The computer records about Lincoln aren't going to be totally accurate. There's still a lot of speculation about him today. Whether he was really that much of a humanitarian etc.
The only ones who tend to speculate on the true nature of Lincoln's character in order to cast him in a bad light are those who are more likely to wear white hoods and burn crosses. The amount of first hand documentation we have on the Civil War, and on Lincoln himself, is so extensive it's mind boggling. There have been over 400 books written about Lincoln- more than on any other historical figure in history. If any man deserves the high praise history has bestowed upon him, it's Lincoln.
