Radicalizing Egyptian Islamist youth started or rather completed

With death toll rising, with their leaders killed and arrested the MB and other Islamists factions will lose control over events and disgruntled youth will do what anyone who has experienced death and mayhem, anyone who had seen loved ones, friends, classmates, acquaintances, revered scholars killed before them would often do. They will arm themselves and they will face the army with force. Some will be more radicalized and will not distinguish between military and civilian targets, a mosque, a church, a shop, a night club, a tv station, or military barricade. They have been called terrorists while peacefully marching, so a word like that will not matter to them. They have been killed while peacefully marching, so threats of being killed will not matter to them. They have been depicted as non-Muslims while peacefully marching, so appealing to religious ideals will not matter to them either. They have been dehumanized while peacefully marching, so calling them beasts will not deter them. They have been denied peace while peacefully marching, so even when sincere calls to peace come, they will not heed them. 

It is not difficult to see how you can produce people like that, and it is not difficult to see that that process has been completed in Egypt.
