Well, it's a shame. In person, the guy seemed really nice. Yeah, he did/does some really weird shit, but whenever I saw him in interviews and signings, he was always so cool and about the fans.
That said, I think Kai just has to be tired. Tired of the work with little recognition. Tired of all the bad publicity. Maybe even just tired of the bodybuilding game. Hope he gets his shit straightened out and the guy can finally be happy.
