I'm sorry, but I have a VERY hard time believing that anyone is so
dense that he or she would think that killing peaceful women and
fisherman was anything but cold-blooded murder.

And really, does it matter if the murderer was warned not to do it? Of course not. Anyone with a sense of morality does not sit by making sure a murderer understands what he's doing is wrong, while the murderer continues to slaughter the innocent. If it's one more innocent life vs. the life of the murderer, I think the moral course of action is clear.
