"Babylon violated diminishes Alexander; Rome enslaved diminishes Caesar; massacred Jerusalem diminishes Titus' Tyranny follows the tyrant. Woe to the man who leaves a shadow that leaves a shadow that bears his form."
Victor Hugo - Les Miserables
French dramatist, novelist and poet (1802-1885)
The above quote is all-encompassing. It talks about the evil that men do that lives after them, scorning tyrants who leave devastation in their wake.
