It is the lack of education everywhere. In every field of life, not only in science.There is no justice in the society in Pakistan two different kind of education system that are producing two different classes on top of so many sects.Those who have the upper leg they have everything but the poor, even the government is acting like we are not responsible for your misfortune. We have to teach the youngs and old both first proper teaching of Qur'an.When they learn the right thing ,they will act right,and know what are they doing wrong then they will be able not to select corrupt politicions who further are responsible for the distruction of the country and society as whole. If they follow the true teaching of Islam then they will be able to change the education system in school and colleges and other institutes.I'm sure the good work is contagious as the bad too. They need courage to say know to the wrong ones but if a person is doing so many wrong things how he could stop others from doing wrong. We need a true leader, right educated ,couragious , honest and a competitive person most of all to have the ability to encourage the Nation how to be united in good work, No mater in how many sects we are divided the right cheracter will attract everyone even the bad ones and the enemy too. It was the character of the Messenger who changed the Arabs.
