I don't think there's eternal shame to dole out. I think it's perfectly equivalent to say if you give someone lifelong trauma that the result should be lifelong consequences, including that people don't want to affiliate with you.
Restoration is a consequence. But additionally, I don't think anyone should be morally obliged to befriend someone who did something against their moral code. For example, if I had a friend who I understood to have committed CSA there is no timeline of which I would be okay with continuing to be their friend.
