I don't think you can draw that conclusion so readily to be honest, he's being charged in America, the SEC are incredibly, incredibly alert to all attempts at commercial insider trading. Lewis believed he could get away with it because the amounts traded by the people he was tipping off would be so miniscule by comparison that they would never be investigated by the SEC in the first place. Like it or not, a lot of us have ambiguous morality when we're doing something wrong in order to help someone else, guilt is not nearly as much at play when you don't see yourself personally benefiting from any wrongdoing, he probably fancied himself as playing Robin hood.
I'm not condoning his actions, he's a fucking idiot and will pay for it dearly, but it's very vanilla compared to the exploits of, say, Abramovich, or the Saudi royal family.
