I don't view those two goals as inconsistent. Obviously juvenile justice prosecutions generally in Canada, in my understanding, take place in light of international law norms concerning respect for the best interests of the child and so forth. So a juvenile justice prosecution in Canada would presumably be undertaken with a view towards a rehabilitative sentence or another appropriate sentence, given his age at the time of the offences. I don't think due process for justice under Canadian law is in any way, shape, or form inconsistent with the achievement or attainment of a rehabilitative objective.
