When advising the 'white rabbit' twitter accounts back in the early days of how trials should be conducted and what punishment should be dealt out, I laid it out as the following:
Abusers can either:
1) Admit to the crime, receive witness protection and 'go to jail', or
2) Wait until their satanic buddies stab them in the back and murder them in order to prevent the truth from getting out
With those who admit the crime, my further proposal was the punishment was *victim directed*. It is not our position to determine what to punish them with because we (or at least I) did not directly suffer under their hands.
If the victim wants to forgive, then by all means (the perp simply goes to jail - they're too dangerous to be re-released into society). If they want punishment, then it's as they direct.
In a conflict between two victims preferences, the punishment overrides the forgiveness (the abuser is punished as a result of the other victim, not as a result of the one who gives forgiveness).
Regardless, we might not get the luxury of picking what punishment can be applied (how do you punish someone in another sovereign country?). It might be so difficult to maneuver through that we have to take whatever punishment we can get.
I personally don't subscribe to the 'forgive all' philosophy, and operate on a 'fitting punishment' approach. If I see a criminal making genuine amends, then their punishment is to continue making amends. If, on the other hand, they're unrepentant, I'd much rather they experience what they did to others.
But that's not for me to decide. If jailing (rather than punishing) one means we can book a couple more into custody, then I'd rather go the 'less is more' route.
My only job here is to facilitate the possibility of that happening. It's up to the victims to make their wants known. See as a bit like a mafia op where the mafia work for the people. You want Johnny to fall down some stairs? He falls down some stairs. You want Johnny to meet his maker? He meets his maker. You want Johnny to be given a light dusting and then sent on his way? He gets a light dusting and gets sent on his way.
Remember, if you don't punish them, you're only sending them the message they're free to always do it because even if caught justice is not done.
