Lewis Powell: The conspirator who was "different."

[LincolnMan]

While glancing through the Time Llfe book The Assassination: Death of the President from the Civil War series, I came on some notes concerning Lewis Powell (the book calls him "Paine") on page 154:

What astounded onlookers about Paine was his dignity, his coolness and his apparent indifference to what was going on in the courtroom. He was guilty of the attack on Seward, he said, and he wished they would "hang him quick" and get it over with. Proudly erect and beautifully muscled, he passed much of his time in the courtroom staring dreamily out of the window. He never wept but he laughed once-when he was requested to try on the hat he had dropped in Seward's bedroom. Of all the defendants, he was the only one who throughout the trial appeared perfectly at ease.


What do you think accounts for his behaviors? He, apparently, was not like the others at all.
