My bro, Someone had to do sth to stop this madness that has been going on for about 3 years. Egyptians stood up for the first time in 2011 after long decades of oppression and corruption, yet they paid dearly to get their own freedom. Afterthen, the revolution which was carried on by youth and poor people who are not members in any parties got hijacked by well organised parties that had little to do with the revolution like the MB and other opportunistics. They failed their very first experience with democracy and elected two candidates who reached the finals, the first was an another Mubarak and the second was an MB. Since most Egyptians knew Mubarak they turned to the MB who won with a slight majority and gave them a chance. Morsi started grabbing power to his own even more power than Mubarak had, and failed to fulfill his promises and yet turned Egyptian lives into worse.
Egyptians realized their mistake and determined to rescue their revolution. Someone had to step in at that moment to bail out the country and no one can do so but only the army. For your information, Egypt lost $83 bn from constant protests, lost state prestige, lack of services, security and almost every single aspect of life has been getting worse.
If Mosri still in power, Egypt will be collapsed.
Nevertheless, Egypt will get better. The peaceful treatment has messed up the country, the other only choice is to restore state prestige by avoiding killing innocents as much as possible. But those who attack and instigate has to be stopped.
Again, there was no other choice.
