Moral and ethics differ from area to area, thus it can be a matter of local culture.

Greater moral and ethics may depend on situation, does one sacrifice the many for the few, or the one? Sometimes the goal outweight the means, and vice versa.

Chruchill in WWII, was in a dilemma, he had to sacrifice a city to the german bombers, as he recently had broken the enigma coding, but if he recused the city by evacuating it, he would reveal that the enigma machine was deciferd, so he had to choose the lesser evil.
