But if it is utalitaria, what would you say to kamikaze bombers? aren't they doing something thats utalitarian for their culture?
There is no such thing as "utilitarian for their culture". It may be benefitting their culture or may be not, but while determining the ethical value of it, you look at the entire picture.
Does that make them more superior to other culture?
Of course not, since what they're doing is unethical.
But on the other hand, remembering your predictions about the war in Iraq's ramifications on the surrounding regimes, and their accuracy, ala "Jordan is going to fall in a couple of weeks", those organizations you refer to might very well be pink Zebras munching on beautiful plastic orange lettuce.
