Hi,
I think it's pretty marginal given that he looks totally insane, you likely shouldn't bet the turn to begin with if you don't know what to do when he raises again.
As played i'd feel a lot better with AJ i'd probably just jam over his turn raise provided his stats are at all representative of his play so far. I don't think going broke with KJ is bad either, and i'd fold it if that was the first time i'd seen take a c/r line.
Hope it helps.
