No, he didn’t. Not by any logic that doesn’t also implicate every other executive, employee, vendor, and customer of every health insurance company, plus a huge number of other industries. To the point where the blame is so diffuse that it’s a pointless exercise.

Edit since I can’t reply: if “murderer” means someone who takes actions that have nth-order effects of someone dying, with no reasonable or discernible limit on n, then we’re all murderers and the term means nothing.
