Why do you think bolivar calls sapin an unnatural stepmother?

Bolívar refers to Spain as an "unnatural stepmother" to emphasize the betrayal and oppressive relationship between Spain and its former colonies in Latin America. This metaphor suggests that, instead of nurturing and supporting their growth, Spain has exploited and stifled the aspirations of its colonies. It reflects Bolívar's belief that Spain, as a colonial power, failed to fulfill its responsibilities, leading to a longing for independence and self-determination among the Latin American people.
