Watch? Why would I want to watch another human being losing their life? I don’t care who he is or what he did, seeing someone die is not entertainment.
To watch or not to watch is a personal call. The video might be instructive to others. I watched the Daniel Pearl and Nick Berg murders to steel my resolve that the perpetrators of the “religion of peace” were my enemies. The videos were gruesome to be sure but violent death is quite commonplace whether you choose to acknowledge it or not.
