Has any government ever viewed their own actions any differently?

Everyone sees themselves as the good guys, everyone justifies what they do as the right thing from the biggest empires down to the smallest country. American, British, Soviets back through all European empires to Romans and beyond.

This whole good vs evil of the current global empire and the war names they give to operations is laughable. Yet they say it with a straight face and it is lapped up by those who get their news solely / mainly from the mass media
