I know you're being facetious but it's impossible to know - the chances of reoffending obviously increase without intervention. It's why I find it really difficult to get on board with the idea of punting him to Getafe or wherever will take him.
Say he leaves permanently and he reoffends having avoided scrutiny + having his behaviours and emotional responses challenged (we don't know if he'd have to undergo any form of psychological intervention if he came back, feels more likely than not if they had hopes of convincing the public of genuine contrition but who knows), will people be vindicated in wanting him to leave or will it be seen as a missed opportunity for accountability?
Yeah, it's deeply unpleasant.
I always feel that where there are allegations of violence against a person it must be cleared up by the process. I know sometimes that's not possible because of the victim, but I feel decades of neglect of the victims is one of the biggest factors there. Fear and shame are part of it too, which is why we have zero tolerance for anyone casting shade on the victim or her family.
