From what i read it wasnt his fault the guy he was wrestling botched a move.
It wasn't Khali's fault...nor the student who got killed. It was the trainers fault...and the word "botched" is the wrong word to use and to be honest, I'm insulted you would use that word for the sitution.
The trainers at the gym had Dalip work with some of their students. I think the move Dalip was doing was the double choke slam. The kid went up, and Dalip threw him down...but the kid didn't bump correctly. He was still new, he didn't have bumping all the way down yet and the back of the kid's head smacked the ring. The kid knew he was hurt and told the trainers that he was in a lot of pain. The trainers didn't care and told both of them to do it again, so they did....and the same thing happen, but this time the kid got KO'd and died later.
