Demonstrating my point pretty well, thank you. You're so off kilter by this idea that you're conflating two very different scenarios - the criminal justice system is rather different than national defense in a number of ways, but your emotionality about the subject is preventing you from making a reasoned argument, and you're flailing around trying to make something - anything - stick.
Which is exactly the opposite of what any person should want from a criminal justice system. We shouldn't want people desperate to extract revenge, but rather people who want to minimize the overall harm done to society.
If I am ever charged with a crime, I want people who aren't going to let some flowery description of what people THINK I might have done causing them to undervalue evidence that is exculpatory. Wouldn't you want the same? Let's say you were accused of raping and murdering a child - would you really want the public's demand for revenge, the jury's disgust with the crime, the prosecutor's inflammatory rhetoric to sway the jury, or would you rather the evidence be evaluated instead, emotions put to the side?
Further, were I actually convicted of a crime, I would want people to decide on what to do with me to be people who are able to resist the urge to merely punish me, but rather seek to rehabilitate me or, if they believe it isn't possible, to be able to recognize that removing me from society so that I can't hurt others while still preserving the ability to release me if I am later found to have been innocent is a vastly better solution than simply killing me, and shrugging it off if I am later found innocent. I can't imagine that you would want people who want to hurt you just because they're enraged at what you did deciding on your punishment, but maybe I'm wrong.
And finally, more harm than good is done by our system as it stands now. This is proven by the fact that other nations with more civilized criminal justice systems have lower crime rates, lower recidivism rates, and overall better outcomes when it comes to people who have interacted with their criminal justice system than we do. If revenge is the best way to handle this, then why do countries like Norway have better outcomes, when everything about their system repudiates the idea of punishment and instead focuses on rehabilitation and the greater public good? If you aren't aware of the evidence I suggest you educate yourself; if you are aware of the evidence then again, you're action on emotion, not reason, and that is not a good thing when talking about a criminal justice system.
Sneer all you like at the idea of doctors and therapists being involved, but the facts - and they are facts - are that approaching criminal justice with the idea of rehabilitation and repair works far, far better than approaching it with the idea of extracting revenge.
