Democracy is generally a good thing. It is generally better than the tyranny of a despotic ruler. Generally, not always.
Sometimes, democracy can bring about a worse tyranny. The majority can install a government that is oppressive of minorities. Without a real desire to limit the power of the majority and an iron clad agreement to do so such as a constitution with required judicial oversight, democracies may become more oppressive of minority rights than even some of the worst despotic monarchies.
Free elections result in the will of the majority of voters coming to pass. If the will of the majority is to assure rights and liberties for all, things are going to be just fine. If the will of the majority is to seek revenge against the minority that previously ruled, things are going to be very bad for the minority. If the will of the majority is to impose draconian religious restrictions, if you are not part of that majority and not interested in living under such restrictions, you might not like majority rule.
The situation in many countries in the Middle East today is as follows:
A nationalist, sometimes fascist, ruling party supported by a minority of the overall population, but which controls the military, is headed by a dictatorial leader. These nationalists face Political Islamist groups of substantial size.
Political Islamist groups are those seeking to install sharia law as the law of the land as opposed to modern civil (secular) laws. They also seek to coordinate their efforts across national boundaries in an effort to create a larger Arab led Islamic entity, sometimes called the “Islamic Caliphate.” Political Islamists often harbor dreams of restoring Islamic empires of the past and reclaiming for Islam lands lost to Western powers or to Western ideals.
A relative minority in most of the nations in the Arab world favors secular democratic principles and fewer still favor those principles in such a way that they would be willing to fight and die in order to protect the rights of hated minorities.
In the conflicts going on in most of the nations where unrest is found today, democratic protesters relatively few in number, are being backed by political Islamists who hope that by joining with the democratic protesters they might be able to overcome the rule of the nationalists. For those interested in freedom and democracy following the fall of nationalist governments, this should be of grave concern because the combination of democratic protesters and political Islamists working together will lead to the political Islamists coming to power and simply installing a different set of anti-democratic laws and oppressive rules.
The vital idea to note is that a modern democracy requires that the majority be willing to fight and die in order to protect the rights of hated minorities. No nation failing this test may call itself a free nation. Tyranny of the majority is still tyranny.
The only way to avoid a tyrannical alternative to the nationalists dictatorships currently ruling in many Arab states is for the nationalists to work with those seeking democratic reforms and for the two of them to create together a free society that values and protects the rights of minorities.
Failing this, nations will simply move from one form of despotism to another, suffering and violence will continue, and the Arab world will continue to deteriorate further down a path of hopelessness and hatred.
