100% agreed. Somehow large corporations get away with a diffusion of responsibility. Enough people are involved that it's hard to blame one person. But certainly for issues resulting in death, I don't think responsibility should be diluted.

If 10 different executives knew or should have known that their decision had life-critical implications, then I think all of them should face the appropriate penalty. (Here, I presume it's for involuntary manslaughter due to criminal negligence.) And I think the same penalty should apply to developers who knew or should have known that their actions put lives at risk.
