I'm not sure rape being normal kid behavior is considered subjective, that would imply some would think it's okay which I'm almost certain is not the case unless you're a complete psychopath.
And I'm also not sure a college campus is the best place for a convicted rapist who preyed on a drunk girl. An exception could be him not being able to live in student housing, receive financial aid, and the first time he's caught at a party with alcohol he's placed on supervisory probation, then yeah maybe. Although he did basically ruin half her college experience which is drinking and socializing, I doubt she'll be comfortable doing that around dudes anytime soon.
I don't really think you understand what he did, classifying it as a "mistake" is almost condescending. I've known girls that had everything going for them, were raped and they had to drop out of school because it destroyed them, many turned to drugs and were suicidal because of psychological trauma. Not saying that's whats going to happen to her, but it's extremely common and I have a difficult time saying "he paid his time, let him be", when those very things you mentioned he should be entitled to are going to be a difficult process for her.
I'm all for justice but also rehabilitation, the kid should get a chance to make up for his mistakes, but the entitlement train left the station when he decided to commit one of the most despicable crimes in nearly every culture.
