Some Murder Or Other

If once a man indulges himself in murder, very soon he comes to think little of robbing; and from robbing he comes next to drinking and Sabbath-breaking, and from that to incivility and procrastination. Once begun upon this downward path, you never know where you are to stop. Many a man has dated his ruin from some murder or other that perhaps he thought little of at the time.

-- Thomas De Quincey (15 August 1785 - 8 December 1859), English author, "Murder Considered as One of the Fine Arts" (1827)
