And my sticking point with rehabilitative justice is routinely "okay, but what about the people who know exactly what they're doing and are doing it for fun and are categorically uninterested in stopping?

I just want to say as someone abused by serial abusers who did it on purpose largely for fun, yes this I struggle with this issue immensely because my abusers cried crocodile tears in public, framed themselves as victims, and have gone out and abused again and the particularly savvy ones use social justice rhetoric to get away with it and even get people to support them as they victimize others. And how do you stop that?

I grew up in Cults of Personality, which is different from Catholicism in important ways, but Cults of Personality love "love the sinner, hate the sin" so it's... complex, because my survivor trauma, and also my terror of the unjust legal system which is stacked against me and caused me harm based on what I am (on a different metric), smack into each other hard and that's not even getting outside my own head into other human beings. Your desire for nuance and to understand this is making ME think deeply, so thank you.
