[As he makes an aside about anti-pope Bergoglio, I also make a comment:]

6:18 "because we have means to imprison someone for a long time"

There were oubliettes in some places when St. Thomas penned his words ...

The longer you imprison some (like the closer the verdict comes to earlier ones on death penalty) the more frustration is that person going to feel for longer and longer time. Note, the frustrations in death row are more due to prolongations after prolongations than to death penalty itself as such.

And the more people who are treated that way, the more people you need who are "capable of dealing with them" - one desideratum being at least apparent humanity, but one being also prudence about a dangerous person. Is society best served by getting more and more of those who have seen too much evil in fellow men of less fortune than themselves?
