Robbery vs murder

Robbery on the seas is considered as an offence within the criminal jurisdiction of all nations. It is against all, and punished by all; and there can be no doubt that the plea of autre fois acquit would be good in any civilized State, though resting on a prosecution instituted in the Courts of any other civilized State. Not so with the crime of murder. It is an offence too abhorrent to the feelings of man, to have made it necessary that it also should have been brought within this universal jurisdiction.
