There's never going to be a scenario where everyone agrees 100% of the time, but I think in this particular case, with some of the people who accused the group of doing this "behind their backs," we should definitely be as clear as we can, and that there is always a possibility that scientist interference may very well be on the table. We can't control the scientists, and they may find that our punishments are too lax in certain cases.
Let's be real here, we will always give second chances to those who show genuine remorse. How many chances have Magneto and Loki promised to be on their best behavior?
