I do agree with you partially. The part you didn’t include is that this is a business and it is shareholders money, he must declare it and there should be limits to CEO to do such. It is the 2nd loan asked, for what? Can the company afford it? What if we did inherit a gambler on this CEO!!! There should be a procedure, this CEO didn’t follow or explained nobody none.
Despite of the ethical part, you know it is wrong what he is doing: The Devil is within the details
