"By force of will he turns his gaze upon the seething horror bellow us on the hillside.
Yes, he feels the icy touch of fear, but he is not cowed. He is Superman!"
Solves two problems,
1) Clark gets his powers from day one
2) We can stop having the Kents as being the reason Clark is a good person
actually it's three
- NO MORE SUPERMAN GOES EVIL BECAUSE OF ANYTHING... He is an inherently good person. He can still screw up and do the wrong thing. But he us established as not being mean-spirited or cruel by nature.
In the classic Superbaby stories, Clark is always doing things that at first stump his parents but then they realize his reasons and he's being super-smart.
The only fly in the ointment is the way Superbaby talks. He doesn't seem to have mastered the English language. However, I recall a fan theory in the letter columns, which suggested his stylized way of speaking was because he had invented his own syntax. Put simply, Clark considered his use of English superior to his parents' and saw no reason to change.
