I'd say the liberation of a country from occupant forces is always a pretty worthy cause to anyone but... ...well, you.
Also, killing even cops and soldiers occupying their OWN population, is something to be saluted, as governments are nothing but tools of oppression (democratic governments being populistic versions of them). Each time one of those evil bastard cops or soldiers gets killed, I celebrate every grain of gained true freedom for a full day.
