Bayer has got to have the worst history of any company still around. They used concentration camp slave labor and performed medical experiments on them as well. Then someone who went to prison for 7 years for war crimes was appointed the head of the board when he got out of jail. Of course they also invented heroin as a "non-addictive substitute for morphine."

Or Fanta. ;)

All of these companies should have been shut down for immoral practices. If somebody acts shady in the past, it doesn't exactly reassure me to trust them in the present.

It's a view I used to hold, but now I'm not that sure of it. First, a company today is not run by the same people as it was 40 or 80 years ago. So the question is, how much of that immoral past is in the "company DNA", and how much of it was just the old management? Secondly, shutting down such company would work if and only if you went and jailed people responsible for atrocities. Otherwise, they'll just join other companies or start new ones and continue to do evil. And since what you really need is bad people in jail, you may as well just leave their company be.

The ecosystem of the company is what creates the immoral behavior. It's the combination of the management, shareholder expectations, etc.

If the shareholders are lax in demanding moral behavior, then immoral behavior will result. The company should absolutely be shut down.

Actually, nobody will want to hire them. After all, nobody wants to lose their money in a company that was shut down.
