<< Even bourgeois jurisprudence teaches that of the three bases for punishment - deterrence, rehabilitation and retribution - only the first two are valid. >>
If bourgeois jurisprudence teaches that--and whom did you have in mind? That covers a lot of ground--it is wrong. I think that retributivism is correct. Otherwise, among other things,you cannot explain why it is wrong to punish the innocent.
Besides, you yourself do not believe otherwise. You would like to see the capitalsit slimebags strug up because you thing that they have done evil, not because you think it would deter others. In the world where they could be strung up, others would have no opportunity to engage in that sort of evil.
