So, are we allowed to open the discussion on what to do with people who are anti-social, have no intent to ever be a productive member of the society and are plain harmful to the said society?
As much flak as it will earn me, I often times regret that the concept of "outlaw" has died out in our culture. If you have law for nothing and are clearly not afraid of whatever retribution it can throw at you, why should you be afforded a process of that law?
I also sometimes wonder about the death sentences passed by the Polish underground state during WWII. In essence, yes, state-sanctioned murder. Wrong? Well, more often than not, I think it was justified, given that the targets were collaborationists, Nazi officials known for notoriety, etc.
Shouldn't the society protect itself? Obviously, the ideal approach would have been to make sure everyone wants to be part of the society, but when that kind of take on it goes belly up, then what? Water cannoning them is going to wash away the taint, is it? Tomorrow they will wake up rinsed men and women and become stately clerks?
