I saw that video earlier last week when the master of the dojo (the fat fuck) posted it on his own youtube for some reason.
The guy is assumed to be Schizophrenic. Blythe had written a lot about him on the info section of the video and described how he was a regular nuisance around town. He invited him to his dojo so they guy could teach him his moves, but really had planned to beat him down regardless.
What's most infuriating is how that lumpy "black belt" is even considered a black belt at all. He basically just goes for groin kicks while the Schizo dances around him, then reverts to street brawling and cheap shots once the other guy gives up. Fucking pitiful.
I know the guy probably died of head trauma but I'd like to think he's sparring with Jesus right now.
Edit: The irony of it all is tragic. Martial arts is intended for self-defense, but the guy's kind-hearted pacifism prevents him from using it when it's most necessary.
