In secret, an unemployed man with poor job prospects uses his savings to buy a large term life insurance policy, and designates a charity as the beneficiary. Two years after the policy is purchased, it will pay out in the event of suicide. The man waits the required two years, and then kills himself, much to the dismay of his surviving relatives. The charity receives the money and saves the lives of many people who would otherwise have died.
Are the actions of this man admirable or shameful?
"So from a libertarian standpoint, this is not an admirable act -- he forced the shareholders to do something they didn't want to do."
No, he didn't. They wanted to offer a life insurance policy. I'm confident that they're not thrilled about having to pay out, but they're not being forced to do anything against their will - only to keep to the obligations they freely entered into.
