Who is Sembeba from Left to Tell: Discovering God Amidst the Rwandan Holocaust and what is their importance?

Sembeba is one of Pastor Murinzi's children. He personifies the thinking of extremist Hutus. He quotes his education, which was biased and filled with hatred, to rationalize the genocide. Although Pastor Murinzi tries to reason with him, he will not be swayed and continues to be filled with hatred.
