I think your comment describes a consequentialist take on the subject of dishonesty and implicitly argues that the deontological version is incorrect. I agree with that conclusion, but I don't think it says anything unusual on the subject of dishonesty in particular.
You think the right to self defense is consequentialist? That's the first I've heard about that.
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?
