So, now that we've gotten ahead to the current episode, it becomes clear that Bizarro Kal-El's problems were an acidic mixture of his tendency to pontificate (shared with Clark) and the fact that prolonged drug abuse left him unable to think coherently. If he had just brought the stupid pendant to Clark in the first place, explained about Ally, and asked nicely for help in destroying said pendant, then *none* of the subsequent problems would have happened. Kids, this is your brain on drugs!
He was also trapped in that mine for weeks surrounded by X-Kryptonite and sharing those migrane-like vision headaches with Superman. Added to his existing mental health and drug problems there's no wonder he was behaving erratically.
