I know the feeling of victimization, and the terror while it is happening. I truly believe that there is no forgiveness for them.
Also, it takes a special form of defect to overlook that obvious fear, and keep victimizing someone. Even drunk, even young, and reckless. I'm sure there's lots of normal men, who've never been there, and can make excuses about her getting cold feet, or changing her mind after the fact, but someonee with a shred of empathy, and decency can't do that. Can't attempt to rape a professor, ignoring her obvious fear, then high five, and grab some more beers afterwards.
It's easy to make excuses, but honestly, there is no excuse, and guys like that don't just get better. They tend to get worse (In this case through co-escalation) even if they don't get rich, famous, and powerful. What I can't understand is grown women, who have been victimized, turning around to defend such obvious monsters, and their flunkies. Much less with such flimbsy excuses as using underage drinking to justify attempted rape.
When they really should know better.
