Islamic Exit?

The story I have linked here is fascinating.  It details two cases where young Muslims have left Islam as a result of their realizing they were being used to kill.  The first case was celebrated because the father of the Muslim man is also a leader of Hamas.  In the first case, the young man converted to Christ after studying the Bible alongside the Koran.  In the second story, the young man simply feels cheated because of the violence of Islam.
