I surmise you have justification for this assertion other than your opinion? And you are conflating "causing suffering to the wrongdoer" and "remove the wrongdoer fron society" as though they were inseperable, when it is the justification for the former that is lacking.

And in your world, incarceration is seperate and distinct from punishment?
Dark Hellion wrote:The line where a crime crosses from desert of rehabilitation to desert of punishment is a major sticking point, of course, as there is little we can do to determine all the exculpating circumstances.
Alas, you have not shown there to be any such line at all.

One is committed within the bounds of society, one rejects such bounds and in rejection of society gives desert for removal and rejects the rights and privileges that society grants. There are crimes that the thought of which should be so heinous that commission of them is a statement that you wish to leave the protections that society grants, and as such you wish to be treated in the same manner than you treated your victim. In the end, by choosing to commit such crimes, they give the punishment to themselves. If there is deterrence, it is a bonus, but their suffering is promised them by their commission, and if they feel their rights are infringed, fuck them, because they fired the first shot, so to speak.
More rah rah rah without any logical backing. Unless, of course, the first few sentences were meant as logical backing, in which case you are question-begging.
"Given the punishment to themselves"? Bullshit. And I love the way you simply ignored my argument above, which touches upon this very point.
