I am in favor of treating others as they treat you when it comes to punishment. Beheading is a Middle Eastern thing that ISIS has inflicted on all those who disagree with their interpretation of the muslim faith. A bit extreme, but that is why they call them extremists.
If this is how they wish to levy their punishment then that is what they all deserve. Did you just want to give them a lollipop for all they have done Neverna?
