Over the course of World War I, the revolution, and the civil war, Strelnikov has become so obsessed with his quest to prove himself that he has lost sight of the real object of his quest: Lara. It takes Yuri’s recounting of Lara’s words for them to sink in for Strelnikov, as his inferiority complex prevented him from listening to her when she expressed her love for him directly. Strelnikov dies by suicide because Yuri’s story reveals to him the hopelessness and pointlessness of his situation. In leaving home to remake the world for Lara’s sake, he has cut himself off from her forever, no matter how many revolutionary victories he experiences.
