I understand that mechanically, it's a bitch to get around this, and it does not feel 'fair' as a Fortress player, to have additional restrictions placed on your actions, that historically have not been present. There are some others currently in place as well, that many do not agree with... However I do feel this line from the Fortress help file, validates this specific policy:

"While the means and methods of each group differs, they both have the same singular goal of the absolute preservation of the Light."

It is also in line with other roleplaying games, such as seeking absolution or redemption, if committing grave sins - This specific one, in CF terms, is an easy one for the game to track/identify, and so the immortals to act upon. I haven't seen a great deal of immteraction taking place from the Fort imms, in about 100 hours in the cabal, so this one seems like a low hanging fruit for them to get involved?

I have not been forced into a redemption, so I'm not clear on the full punishment players are receiving for being on the receiving end of example #3 of killing good, if it is something which can be discussed OOC, perhaps detailing this would help.

ie are the individuals being demoted to squire, powers removed, if communer, empowerment revoked, etc.

If it is more roleplaying contrition, and being asked to perform "penance" in some form, it makes sense to me, but I'll wait and see if we can discuss the details of the punishments further.
