Your personal choice of "most tragic" character in the assassination story

[LincolnMan]

I came across this quote by Don E. Fehrenbacher:

"Lincoln is the supremely tragic figure of a tragic war, and not only because of the way his life ended. He rose to the presidency from deeper obscurity than any of his predecessors, only to find himself in the grip of a deadly historical irony. That is, his own unexpected and dazzling personal triumph in 1860 had signalized-indeed, to some degree that caused-the onset of national calamity. For a man sensitive enough to perceive the irony and its bloody implications, there was bound to be, always, sorrow on the bosom of the earth."
