Joseph Story,
Harmony v. United States — Opinion of the Court
“ If he wilfully sinks or destroys an innocent merchant ship, without any other object than to gratify his lawless appetite for mischief, it is just as much a piratical aggression, in the sense of the law of nations, and of the act of Congress, as if he did it solely and exclusively for the sake of plunder, lucri causa. The law looks to it as an act of hostility, and being committed by a vessel not commissioned and engaged in lawful warfare, it treats it as the act of a pirate, and of one who is emphatically hostis humani generis. ”
