There has emerged this narrative that Mark Zuckerberg started out as a hero nerd and lived long enough to become the villain.

This is a narrative of an unawareness of history. Mark Zuckerberg was a crook from the beginning. He got where he got not by being a nerd, but by stealing from the work of actual nerds. Zuckerberg was never a good guy; it just so happens that eventually he treaded on ground the general public actually cares about. (Or maybe not. He's still going quite strong.)
