The bloke chose to go on the show, even getting a doctors report saying it was OK. Then chose not to take his morphine based arthritis medication so as not to affect the lie detector results. Which he failed. So his fiance chucked him out cz he chose to cheat on her.
Then he chose to take his life within a few days of reconnecting with his son and learning he was a grandfather.
We can't blame JK for the bloke making these choices. Sorry. x
