Mohamed Morsi is just as bad as Hosni Mubarak in that he is repressive and he hinders any political opposition. The suppression of Egypt's judges was perhaps the last straw for Morsi's supporters who eventually turned on him when the military rebelled. Now, it is once again up to the Egyptian people to install a duly elected leader before more violence takes hold.
Mohamed Morsi is a member of the theocratic and repressive Muslim Brotherhood, who in his short term as president tried to turn Egypt into a theocratic Islamic state. To consolidate power he even violently attacked protesters, just like Mubarak before him. His track record on human rights and the economy are not good.
