See, I am in two minds about that- why should it come from human upbringing? To me, that kinda implies that Clark needs humans to become a good person - Why can't it be an idea he arrived on his own? It's an interesting take to explore, and I am glad that they explored it.
After all, Donner took a lot of liberties as well, which were then reincorporated back into comics (presentation of Krypton, re-visioning Luthor's motivations and writing him as an evil capitalist, rather than a scientist who grew up with Clark).
