Perhaps. A couple of the past few popes have suggested and teach that capital punishment is "impermissible" currently. This has caused a great deal of consternation, because the Church has long held the opposite. The quirk is that, in an attempt avoid contradiction, the new teaching says capital punishment is not "the right move" in light of modern society's capability to carry out life sentences. In this case, the mega-prison idea seems doomed to failure and when if fails it will be a social nightmare. Even under nupope teaching, these guys should have hung.
