He'd been challenged numerous times throughout his career by random martial artist looking to gain some reputation by beating him. He'd never lost once, and there were almost always witnessess to validate these events.

I'm not in the mood to debate whether or not his methods (or teachings) were bullshit, but whatever he was doing, he must've been doing it right.

As for the conspiracies. I can't say I believe or don't believe them; I simply don't know.

It is possible that someone wanted him dead - I wouldn't have been the first time. And it is also possible that he died by accident.

Whatever the case, what's done is done. The rest are side-details; information after the fact.
