I can't say I condone prison rape. Crime in prison should still be regarded as crime, and ignoring it pretty much says we don't care about reforming such rapists -- in fact, we reward the worst of the worst by letting them practice their "craft" without further repercussions. And besides prison rape functioning as a de facto cruel and unusual punishment (one that many Americans want but will not own up to by making it "official"), you can even get into the territory where the result is even worse than the original crime. Hate-crime murder is quite bad, but violent rape leading to an HIV infection that gradually kills a person (sort of a protracted murder with long-term agony) feels like a step beyond that. It's not to say that there shouldn't be long-term consequences, but those consequences can't distract from the original wrong that was committed.
