Sure, I guess it could be viewed as indefinite parole. I'm sure some of these bastards were recruited into Operation Bloodstone or some equivalent.

My point was just that you generally don't need to kill people if conditions are stable enough that you can hold a trial for them. Short of wiping iut humanity, you can't kill your way into not having an "at risk of counterrevolutionary activity" population because that killing itself provides a motive to those that survive to become counterrevolutionaries, whether in siblings, children, friends, neighbors, fellow churchgoers, or people not personally connected but watching from afar and going "that sure is a lot of killing," or "how do I know that this many people are beyond saving?" or "how many more rounds until I am next?" It's a very common response.

There are many valid reasons to kill people, but then stick to those reasons and not this, which is not a valid reason.
