Canada

Spouse of a Canadian nurse who works in forensic psychiatry here! For pedophiles who are caught and charged in Canada chemical castration -is- one of the things that our legal system can order. It seems like you're under the impression it isn't already happening, when it is.

I will note that from what I've heard, pedophilia comes in two types of "flavours": the people who are attracted to minors, and are generally direstressed by it and want it to stop, where chemical castration appeals to them as an option to reduce sex drive and thereby the impulses. Then there are those who aren't necessarily sexually attracted to children, so much as the sense of power that comes from doing these things. I have no evidence, but suspect Epstein et al. to be people with these types of motivations. While the castration can help some of their impulses, there's more to it that requires other interventions. They're also typically not interested in reducing this drive because they don't feel bad about it.

Anyway, gathering more info to better support the folks who don't want to follow their urges, and stop them from harming anyone before it happens is super important. I think the power motivated are part of a larger problem within our society that isn't going to be dismantled just through this study. But hopefully I'm wrong, and we'll at least glean some strategies.
