This is at least as bad as any violent crime. Almost certainly far, far worse by any ethical metric. The only difference between this and normal violent crime is that this is the kind of horrifying malicious crime rich, powerful people commit while assault or mugging is the crime of choice for the poor and powerless. Compare this vs. a mugging. Intent was worse -- he intended to assault millions instead of just one and also profited off thousands of frauds as well as obstruction of justice (code to hide it from regulators). Consequences and damages were far worse than any violent crime, obviously.

But yes, sentences should be far shorter across the board.
