the only video I could never ever watch all the way through was that one where those ukrainian psychos were killing that man with the hammer and screwdriver ?? YOU know the one. They were scrambling up his guts by stabbing in with the skrewdriver and mixing it around, while that man gurgled and moaned?? when they started poking his mashed up nose and crush face with that skrewdriver, I WAS OUTTA there.
I haven't seen that one but the one for me that was hard was an old beheading where the haj is cutting out the guys voice box and you can hear his muffled echoes.
