I answered you about at least two or three times.
It's immoral because it doesn't provide any restitution to the victim.
Vengeance is something that belongs to God to dish out, but vengeance is not restitution.
Restitution is restoration of something that has been lost or taken.
If a victim ends up with eternal life with an eternity of love and abundance then restitution has been given and more and it will be up to the victim at that stage to say if they are not happy with that and want more.
It sounds as if you want time to be turned backwards so that the victim never experienced the suffering caused by the culprit and everything will be returned to that point in time as if the evil never happened.
But the evil did happen and I don't think that time will be turned backwards.
Are you sure you don't want vengeance against the perpetrator? You have mentioned that you don't like the idea of the perp being forgiven by God (if that happens)
