I like the idea of having capital punishment. But it can only be sentenced by a unanimous jury. And each of the 12 jurors will be hanged along with the person they’re condemning. This will be done with the full knowledge of the jurors. They will know that if they vote for death, they themselves will die. Is there some Hitlerian figure whose continued existence is such a risk, is so damaging, is so detrimental to the world that it warrants the state committing murder? Fine. Find 12 people willing to give up their own lives for the cause.
