It is an interesting question. 1) I don't think "corporations" are picking and choosing, there is extensive legal history on this point. 2) Re: "kills someone through their negligence". I think you've abstracted too much for there to be a single answer. I gather you are talking about situations where no identifiable person lead to the death and so there is some sort of "collective" or "systemic" failure that "caused" the death. I think the particular facts matter in those cases and the result is a variety of punishments from fines, to external supervision and inspection, and even in some cases action against individuals that were connected to the faulty decision making. One size doesn't fit all in this case.
