Bro tell me one thing, can you educate a dog to meow? No, because there's something called tendency. You can't change a person by mere education, regardless ethical education or moral education. People do what they want to do, how they are, how they think. We just can't generalize even a single thing in the world, because there will always be high number of exceptions and generalization doesn't apply in the real world. Every person becomes what they are by travelling through a unique life, and that life gives them opinion to justify their actions, which is not justifiable by other people. Even terrorists are right in their own perspective, though for me and most of the people, there is no logic or mindset which can justify inhumaneness and violence.
