Final answer:
Ouanda's decision not to change the piggy infants' method of reproduction respects the theme of life's natural course and the complex emotions involved in parental care as depicted in the provided texts.
Step-by-step explanation:
When Ouanda learns about how the piggy infants reproduce, she initially wants to intervene but ultimately decides against it. Her decision is likely influenced by the thematic elements found within the texts provided, which echo sentiments regarding the natural course of life, the responsibilities and struggles of motherhood, and the intrusive nature of altering another species' or individual's destiny. Throughout the texts, there is a recurring theme of the sanctity of life and the complex emotions involved in parental care, from the nurturing of goats and the horror of human maternity turned into a grotesque suggestion of consumption, to the contemplation of personal ambition (involving barns and weddings) and the challenging questions of a mother's love for her child. These examples illustrate a respect for the established natural order and hint at reluctance to interfere with another being's inherent life cycle.
