What did John Wilkes Booth Mean?

[LincolnMan]

In addition to what has already been said about Booth's statement (to which I also agree)-is there a part of Booth's thinking that he wants to leave a statement for the sake of history that he had the ability to clear his name. I'm sure there was a side of him that knew he was not going to be living long-even though he was on the run-and hoped it would be otherwise.
