Step-by-step explanation:
In the context of the provided references, Ender's realization that he needs to kill Human, a character likely representing a significant being within a fictional community, could be understood as a part of a greater narrative on the relationship between humans and the environment, as well as a critique of human tendencies toward dominance and cruelty. The killing suggested could symbolize a difficult but necessary act for the betterment or healing of the community, reflecting themes of sacrifice, responsibility, and interconnectedness. This act may mirror the themes of ethical treatment of animals and the environment, alluding to a mature understanding of success, which includes the well-being of all beings and ecosystems. Through the need to kill Human, Ender (and by extension, readers) faces a philosophical dilemma about the nature of life, the responsibilities of power, and the necessity of making hard choices for the greater good.
