An idea I had after reading The Other History of the DC Universe # 1, and its related to a discussion we're having over on the thread for that series.
Basically, at one point, Jefferson Pierce AKA Black Lightning, reflecting on Superman, thinks that Clark's weakness is wanting to be liked and accepted by people - with the implication being that this is due to being the last of his kind. He attributes this to Superman's willingness to not rock the boat too much or take any radical action. There's a pointed reference to how this Superman isn't someone who'd demolish tenements in Suicide Slum to force the construction of better housing (unlike the original Siegal/Shuster Superman).
Now, the Superman in this series is clearly modelled after a more mainstream Silver/Bronze Age take on the character - one who's clearly aware of his full origins at the start of his career.
Which did get me thinking - how much does Superman's knowledge of his Kryptonian heritage influence his actions in his early career?
Does knowing he's an alien, and the sole survivor of another civilization, shape him into more of a status quo-ist who wants to be loved and accepted by human society and thus strives to be more of a Boy Scout and less of a vigilante?
Contrast this with the Golden Age Superman, who didn't know he was from Krypton early on, grew up presumably believing he was a human who happened to have extraordinary powers, and was therefore more willing to shake things up and challenge the status quo.
There does seem to be a pattern to this - consider the New 52 Superman, who starts out as a kind of 21st century take on the "champion of the oppressed", and starts the transition to a more 'classic' take on Superman once he learns about his Kryptonian origins.
Now, I don't think the explanation for this is Superman just wanting to be 'liked' by mainstream society. But I do wonder if he feels that, as an alien and an outsider, he doesn't really have the right to interfere too much, even though he feels a duty to help out where he can.
Thoughts?
