Is that clear enough for you? Your statements about incarceration versus death are hard to follow.
You're clear about not rejecting punishment but you're not clear why (is double jeopardy OK with you, do you say that punishment is not double jeopardy, etc., etc.).
It's OK, man, don't worry about it. Have a good day.
I reject the notion that punishment is double jeopardy. But even if I stipulate, for discussion, that for whatever reason "protection from future repeat criminal acts" is the only reason for sentencing a convicted criminal, killing the criminal is not excluded. Re-read #142.
