Why might Christian missionaries have thought it was okay to convert natives to Christianity

Answer: Missionaries are convinced that Catholicism is for everyone.

Explanation:

As the dogmas of most monotheistic religions dictate, monotheism is intended for all of humanity. Therefore, Catholicism is no exception. It was these phrases that were held by Catholic missionaries. They thought that this would bring them eternal salvation afterlife on earth.

They also sought to raise the natives to a higher civilization level. Natives often walked naked, and there were stories of cannibalism being represented. Therefore, they tried to eradicate these phenomena by introducing them to Catholicism.
