The quote suggests a profound moral principle regarding life and death. It emphasizes that those who take the lives of others will ultimately face dire consequences, losing their own life in a metaphorical sense. The act of killing leads to a cycle of violence, resulting in despair and ultimately death for the perpetrator.

In contrast, the quote highlights the nobility of sacrifice, positing that someone who sacrifices their own life for others will achieve a form of immortality. This reflects themes of selflessness and the idea that true life comes from giving oneself for the greater good. The juxtaposition of these ideas underscores the eternal conflict between taking life and giving it away, a central theme in Philip K. Dick's work.
