They did give him a strong moral compass.

Superman is probably the greatest DC superhero, am I right? What can't he do, assuming there's no Kryptonite nearby? I don't know the answers to your questions, though I do have knowledge of his childhood. He showed various abilities that were superhuman. When be became an adult, he adopted the Superman persona to help humanity. Exactly! Luckily his adoptive parents were super (ha) supportive of him as he grew up. They always knew what was best for him.
Discovered and adopted by a farm couple from Kansas, the child is raised as Clark Kent and imbued with a strong moral compass.
