Shots in the sky (1958)

Upon returning home at war's end, a young lieutenant discovers that his family has been murdered by the Nazis. It's all the handiwork of a treasonous "Chetnik," who during the war worked against the partisans on behalf of the Germans. In bitter retaliation, the lieutenant sets about to decimate the Chetnik's family. He stops short, however, when he realizes that the sins of the fathers are not always passed down to the innocent children.
