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

[Thomas Thorne]

Most tragic-Henry Rathbone and Clara Harris. His "failure" to save Lincoln unhinged him and drove him to kill Clara, the mother of his children. The 2009 Washington Post article by Thomas Ruane accessible via the Wiki Rathbone bio says that Clara saved the lives of their children.

At least none of the other persons affected by the assassination had to go thru that.
