Maybe he is elite in ISKA and kickboxing, who cares, I thought he was a Taekwondo guy, what did he achieve in Taekwondo, nothing? This is the Taekwondo board, not the ISKA or kickboxing board, so, again, who cares, not me.
It's obvious to me he (and his coach) has twisted ethics, and no, I have no respect for that kind of thing. When one competes against an opponent one clearly out classes, in a rinky dink tournament, which is most of what he was fighting in in the first video you posted, you do just what you have to in order to dominate your opponent. You don't take advantage of their total lack of skill and experience, going in for the knockout.
Even in he Olympics, the pinnacle of martial arts competitions, American Steven Lopez showed good judgement by not knocking out the Iraqi fighter, whom Steven clearly out classed. Steve did just what he needed to do in order to defeat him, not injure him unnecessarily.
Then in the later videos he is running around in those "rhinestone cowboy" redneck fringe batman cape outfits, ridiculous. But if you like that kind of thing, beating up on the unskilled, raising ones arms high in victory having defeated the weak, adorning oneself in foolish clothes, go for it.
