BRUTE beast, at last you have it! Now we know
Truth's not a phrase, justice an idle show.
Your life ran red with murder, green with lust.
Blood has washed blood clean, and in the final dust
Your carrion will be purified. Yet, see,
Though your body perish, for your soul shall be
An immortality of infamy!

Francis William Lauderdale Adams
