Unlike the slow, torturous sawing you see in the terrorist snuff films which are deliberately intended to shock the audience and cause much pain and agony to the victim.
Either way, children should not be watching them. I saw Berg's death and I wish I hadn't. :(
But you have a real appreciation for what we're battling don't you? It's not like the soft words like "insurgent" or "killed" or even "beheaded" because you heard and saw the true vicious horror with your own two eyes and ears. You won't forget. You won't become a soft American who hears the Media drumbeat "2000 soldiers dead in Iraq" and wants to run and hide. You read of the recent discovery of human bone fragments near WTC and for second you twitch with anger and determination. You're not going to forget. You're not going to be lead down the primrose path of self-annihilation by the next Chamberlain.
Rather than wish you hadn't seen it (and it was horrible, I saw it too) it's better to wish justice come to those who made such bestial acts possible. Your father or uncle or grandfather or great-great-grandmother didn't shrink from the horrors of the wars they faced, did they? Why should any of us allow ourselves the luxury to avoid the reality and wallow in denial, embracing cowardice and willful ignorance?
