Well, I find it hard to believe they'd behead one of their own.
I don't. It would be like finding it hard to believe a suicide bomber would take their own life.
I hate to say it, but being the "right" religion didn't save any of the innocent Iraqis killed by them.
The Islamist are quite evil.
The Whabbists are the most evil of the Muslim "religion" and most of them are in Saudi Arabia.
Saddam is a Whabbist.
All the different sects of Islam prey on the others. They have no moral compunction to NOT behead anyone that does not adhere to their beliefs.
Heck, look at their antiquated laws...Women are shot in the back of the head for being raped...Others have their tongues cut out and their hands cut off, and their fingers too...(a video of Saddam's regime doing that is available on the net).
They are Barbaric, period.
