I saw the video, and just like the rest of them I think they're fake. This one shows inconsistencies to the light casting on his face, while the shadows in the background remains the same. Also the knife cutting is more like knife rubbing. It rubbed on his neck like 5 times before the video fades out. Anyways this is just what I think, examples down below.
There is a ABC part to all these videos.
A = victim gives speech.
B = happens in your mind.
C = head on top a body. (fake head, fake body?)
