I understand poverty and children having to work because their families are poor. My grandmother (the smartest person I ever have known) had to quit school in the 4th grade because her father was killed in a mining accident and everyone had to work for the family of five children to survive. What I can't understand is someone wanting to kill someone who has the desire and ability to go to school. Why would anyone want to kill a child or even a young teenage girl and especially one who had done nothing to hurt anyone else.
Control. Those men cannot control women that easily in their country once they were educated. It's sad but true everywhere. And fear is another way to control people. She dare to stand up and fight for herself and encouraging other young girls to do the same scared the s*** out of them so they wanted to suppress that voice.
