Castration is a reactive solution to ensure that the male does not do it again.
There are a hell of a lot of males out there who will rape.
Can not be stopped unfortunately. And as this sentence shows, even when convicted, piss poor sentences.
There was a case here in Australia where a civil servant allegedly raped an office worker.
Case went to trial, trial was aborted because one of the jurors broke the rules by searching the case online.
No finding was made against the perpetrator.
Justice Michael Lee found that,
on the balance of probabilities, Bruce Lehrmann raped Brittany Higgins.
He gets away with it because of the juror breaking the rules.
