When I was on a completionist playthrough, I hunted down all 17 cyberpsychos and kept them alive, hoping there would be some kind of a meaningful end to it. I actually expected that Regina would work with whoever was trying to develop a cure for cyberpsychosis, and getting all of them without killing them would produce that cure. But there was...nothing. Perhaps this quest chain was another thing left unfinished.
I was very much hoping that by saving all the cyberpsychos Regina (or, more accurately, the people she's working with) could come up for a cure for Lizzy Wizzy's evident cyberpsychosis. I can't believe that wasn't planned; I suspect that was the plan and they didn't finish it.
