In your analogy that'd still be Robin Hood coming from a very rich family, accumulating more wealth that anybody he knows around him, fighting with his best friends to keep more, getting indicted by the most powerful government on Earth because he abused his power... then giving only a very small fraction of his wealth to some starving children while still sitting in his mansions, accumulating still more money without working.
That's not the Robin Hood of my childhood to say the least. To me that's clearly not a net positive.
I do recommend listening to the episode of Behind the Bastards to get a clearer view of the entire process, not "just" imagining a "net positive" outcome regardless of the path that lead to it.
Edit : sorry but while re-reading what I wrote, somehow confabulating the richest man on Earth for years to Robin Hood shows how excellent his PR work was. Like... what the fuck?!
Edit2: oh yeah and Robin Hood would fight for Big Pharma during a worldwide pandemic, ... no, absolutely NOT Robin Hood.
