Again, this is two quotes near each other in the text. In these quotes the Franz rightly judges the Count... (I will note though that the Count at the end of the book has grown beyond this sentiment.)
"Listen," said the count, and deep hatred mounted to his face, as the blood would to the face of any other. "If a man had by unheard-of and excruciating tortures destroyed your father, your mother, your betrothed,—a being who, when torn from you, left a desolation, a wound that never closes, in your breast,—do you think the reparation that society gives you is sufficient when it interposes the knife of the guillotine between the base of the occiput and the trapezal muscles of the murderer, and allows him who has caused us years of moral sufferings to escape with a few moments of physical pain?"
"But," said Franz to the count, "with this theory, which renders you at once judge and executioner of your own cause, it would be difficult to adopt a course that would forever prevent your falling under the power of the law. Hatred is blind, rage carries you away; and he who pours out vengeance runs the risk of tasting a bitter draught."
