"Killing in Good Conscience"

Here is a paper that should be of interest, "Killing in Good Conscience:  Comments on Sunstein's and Vermeule's Lesser Evil Argument for Capital Punishment and Other Human Rights Violations":

In a recent article, Cass Sunstein and Adrian Vermeule argue that capital punishment is morally required if it will deter significantly more killings than it inflicts. They claim that the state’s duty is to minimize murders, and that recent deterrence research shows that state executions, even if deemed murders themselves, can do so. If these findings are true, they argue, the state is morally obligated to undertake such “life-life tradeoffs.”

The logic of Sunstein and Vermeule’s argument justifies not only state executions, but any state-perpetrated injustice that promises to reduce the incidence of similar injustices overall. Recently such lesser evil arguments have been invoked to justify state torture, detention without trial, and warrantless wiretapping. In this article, I identify problems that are common to all of these arguments. My aim is to demonstrate that, however valid the lesser evil approach may be in some domains, it fails when invoked to defend state violations of the right to life and other fundamental human rights.
