From the company's point of view this is correct reasoning. The sooner people realize companies do not have any responsibility to be moral the better

They absolutely do have responsibility. There's no reason we should allow investors limited liability if they are going to be assholes about it.

Corporations should only exist because they are net beneficial to the public!

I do agree that enough companies are unethical that it is reasonable to expect it.

This is just naive. Every company that makes any kind of product has made some kind of trade like this.

Costco sells you knives cheaply because they will not be liable if you murder people with them. If the Costco investors were liable for murder every time one of their knives was used to kill someone, you can bet they would just not sell them entirely.

Just because a company thinks about liability doesn’t mean it’s immoral. Individuals avoid liability as much as possible too (see insurance).

The world is dangerous and “fault” is everywhere.

I'm not sure what your point is. My comment is a statement that corporations do have a responsibility to act in the interests of society, not an analysis of the particular ethics of selling knives or avoiding liability.

So do people, which are the ones that run companies. What’s your point?

It's actually a human thing. When bad things happen, we strongly prefer that they don't happen as a result of something that we did.

On the other hand, if incautiously switching from the former to the latter drives your company bankrupt, the end result doesn't benefit anyone.
