No, there is no clear protagonist and antagonist in "The Interlopers." The two main characters, Ulrich von Gradwitz and Georg Znaeym, are equals in nearly every way. Both men are products of their environments, and both men harbor the same feelings of hatred toward one another. Each of the men hestitates to kill the other, which seems to indicate that neither is purely evil; each man also makes known to the other that he is capable of doing away with the other when he is rescued from his entrapment under the beech tree. However, each man also comes to the realization that he was mistaken in his hatred of the other.
