> shatter trust with the person he purportedly loves most in the world

Well we don't know that, you are not legally required to love someone you are married to and I have no clue what their relationship is like or whether they have any sort of "arrangements". I could hardly care less really since its their private matter.

> just what might he do to you, the customer or shareholder?

I don't really see a correlation between those things. All sorts of immoral degenerates (e.g. Musk, (potentially) Gates and I assume plenty of other lesser known CEOs) have generated massive amounts of value for their shareholders.

It may even be the case that immoral degenerates are the MOST suitable people to invest your money with.
