I like to think of it this way: Christianity started roughly 2,000 years ago. Islam started in 610. Islam is in the dark ages. Now, there have been some notable attempts to reform Islam, such as the formation of the Baha'i Faith.
Islam is a fundamental religion. Well, technically every religion is fundamental but due to the politics of that area there are more of those who identify as ultra-conservative. Christianity has changed throughout the years. New denominations arise from new ideas and new interpretations of their holy books. God isn't dead, he simply changed with the times.
There needs to be a period of grow in Islam, and by growth, I mean secularization (?) of it. Islam needs to grow the same way Christianity has already grown. Modernize, as you will. There is a possibility of Isis becoming more democratic with their approach, but that probably isn't going to happen anytime soon.
George Carlin has a skit where he sites "Jewish fundamentalists, Christian fundamentalists, Muslim fundamentalists, and just plain guys from Montana" for causing a lot of the troubles that arise in the world.
To me, the problem isn't religion. The problem is a very subjective moral code that differs from each person. Until we can adopt a universal ethical code that many have tried to do and failed, and have that code be accepted by every person on the planet, there will always be evil. And there will be evil for a long, long time...
