imagine the most terrible part of the whole punishment is, not the bodily pain at all--but the certain knowledge that in an hour,--then in ten minutes, then in half a minute, then now--this very instant--your soul must quit your body and that you will no longer be a man--and that this is certain, certain! That's the point--the certainty of it. Just that instant when you place your head on the block and hear the iron grate over your head--then--that quarter of a second is the most awful of all.
