Ethics Case: Profiting from Death: "Janitor's Insurance" Is COLI unethical?

If you think there is something unethical about the practice, what is it? If you do not think so, why do you think so many people find it unethical?

Suppose a company provided life insurance to each employee and also had a COLI policy on each employee? Would that settle the fairness question?

Does the fact that from a financial perspective some employees are worth more dead than alive represent a genuine conflict of interest?
