There was a little bit of dickery here, but true superdickery would have been Kal-El going "oh, so I shouldn't have saved you, Dad? As you wish!" and tossing him back into the pit with a deadly meteorite. Since this was the silver age, I suspect that the meteorite would mutate Pa into some sort of horrible insect worm monster who rampages across Smallville until Superboy picks up his room or something.
