They cheated on an arbitrary number in an EPA regulation, with emissions that were completely legal only a few years earlier. You might as well complain that all car companies are killing people because whatever their emissions levels are, it's more than zero, and therefore cumulatively, statistically, causing some number of deaths.
Also, what does it matter if the number was arbitrary or the emissions levels were previously legal? I don't think anyone is arguing that VW broke a fundamental law of the universe.
