I don't quite remember the details, but I think there was something about extending the prisoners lives because what they needed from them was the Vitae, which was most efficiently extracted through torture, not death. Perhaps it was in the note found upstairs of the torture chambers (the office with Alexander's portrait).

Well, it looks like you have researched this a lot, so I'm not gonna attempt to say this is confirmed in any way xP
