Heh, that's fine. You can disagree with me! And I probably am being a little obtuse.
I think the negative connotations of the word probably do apply to "punishment" as it's being used in this thread. Typically I would think of a punishment as a response to a negative action, designed to prevent repetitions of that action. Necessarily, punishment will be worse in response to actions seen as more strongly negative, because we care more about making sure it doesn't happen again. Think of a mother punishing a child for talking back versus punishing them for doing something dangerous that could've gotten them hurt or killed.
And if used in this sense, this matches up with what I argue for: a rehabilitative justice system with a dual focus on protecting society and on preventing recidivism. And of course taking a look at how deterrence
actually works rather than how we intuitively think it might work.
"Punishment" in the sense other folks are using it here seems to have carved off the actual useful aspect, the idea of making sure things don't happen again, and only keeping "worse actions bring more strongly negative results." But "do something bad and we'll do something bad to you," purely as action/reaction with no examination of future results, is quite similar to revenge! We're bothered by revenge because it's simple retribution without regard for outcomes. (And yes, you guys are right, also because it's motivated by emotion and not by a desire for justice. But that's kind of my argument: when we argue for punishment without thinking about actual results or what justice would really entail, we are really just thinking emotionally, similar to the thinking of a person out for revenge.)
