Answer:
Because he wants to keep people under his rule and within the ideology he wants to impose.
Step-by-step explanation:
Radio Mullah is an Islamic extremist, cited many times in the book "I am Malala" as one of the main harbingers of Taliban rule in Afghanistan. Malala claims that Radio Mullah had a radio show, where he presented highly conservative and extremist, unscientific, oppressive and incorrect concepts. He was strongly against education, especially for women, and was even capable of bombing schools and killing people who took a stand against him.
He knew that fighting education was the main weapon for him to be able to control the population and make everyone follow their will, because the lack of education made people believe in everything they heard and did not have the ability to question and opine against wrong things. As such, Radio Mullah knew that a population without eucation was easily manipulated and that was his goal.
"I am Malala" is the book that tells the story of Malala, the Muslim girl who fought the Taliban for the right to study.
