I take by your sarcasm you don't want a real conversation?

But yes, only not ironically. I don't think a state should kill anyone for sake of retribution, no matter how grisly their behavior. In fact, I think retribution shouldn't factor at all into how a state manages those who break law or engage in antisocial behavior.

Is that a conversation you want to have? Or is snark the only thing you know how to do?

ETA: It sounds like you may not know this: Summary execution is killing someone without due process. Generally, that's a crime internationally, and regarded as a war crime.

I assume you would want Hitler to at least have a trial at Nuremberg, if he was captured, but feel free to correct me.
