Why?
Radio Mullah puts in so much effort to discourage people from going to school?​

Because an uneducated population would be easier to manipulate.

Explanation:

Radio Mullah is an Islamic extremist featured in the book "I am Malala." In this book, we can see how he made the population believe that reading books, watching movies, dancing and even going to school were sinful things and would bring God's punishment in people's lives. Of all the things that Radio Mullah claimed were sinful, education was something he strove to fight, going so far as to bomb schools. The need to prevent people from studying existed because Radio Mullah needed the population to be easily manipulated and this would not be possible if people had education, as education promotes reasoning and right thinking, which prevents people from being manipulated.

Importantly, "I am Malala" is the book written by Malala Yousafzai, where she tells of the Taliban domination process in Afghanistan and how she fought to guarantee the right to education.
