This isn't complicated nor is it even controversial. Problem is that corporations have so much power that they can subvert the system to be sure none of the above ever happen.
If there was intent I would also say it's intent on the part of the driver (pending a mental health examination) and not on part of the company.
If the company instructed the driver to hit a car on the tracks they would be a criminal organisation and they should cease to exist.
In the case of GSK they committed fraud by lying to their customers. It's not intentionally killing someone but it's definitely endangering lives and it should cost more than 3B
Otherwise, managers of a company, could do criminal activities like for example commercialize medical products for one purpose, but that were not medically approved for what they are being sold for and face no time in jail, just financial penalties...No...hold on..wait a minute!!
