First of all,I would advise you stay calm.It is just an intellectual debate which demands logical reasoning,not emotional outburst.

Yes,Islam provides a complete code of life but Islamic Political System requires immense knowledge of Shariah and Fiqh.And in the absence of such knowledge,every leader tries to implement Shariah laws according to his own interpretation.And whenever the state becomes sectarian,menace of extremism starts to take roots.And this process started in Pakistan when Zia government became sectarian.
It is correct that Morsi enjoyed majority,but he wasted his political capitals by using tyrannical methods to grasp power.And a leader is one who anticipates the crisis and successfully handles the crisis.However,Morsi lacked such leadership skills.
