Let me first cover the good part first. I salute this guy for saying that if his son is a terrorist, he should be killed.
The Bad part. He is a school teacher, he should know that it is difficult to raise 11 children and it will not possible to provide good life (i.e. food, clothing and most importantly education) to all children. Why did he make that mistake. Even though he is not responsible for what his son does but don't you think he is indirectly responsible for this?
I can understand if an illiterate person has 11 children but this guy is a school teacher. I really don't get it.
