hate who she was and what she did 11 years ago. don't hate who she is now and what she did by coming clean...
Some things you can excuse. But this?
Seriously?
I would put that on the same line as having AIDS and intentionally infecting other people. Or maybe even murdering people (and spare me the "he is not dead"-line). It were 11 years. The actual victim's life is over. Even getting a job again should be almost impossible. "What did you do before you applied for this job?" - "I was in jail for 11 years, my daughter accused me of rape, she lied I'm free now" - "Oh ok, we will call you". He is and was innocent, but it won't matter at all. Just because she confessed now doesn't give him back the years nor his life.
What to do now? I really don't know. But letting her go just because can't be the right thing. Say someone infects other people with AIDS. And after 10 years that someone finally confesses and says "Sorry was pretty dumb to do that". Would that be fine to the victim(s)?
Put her in jail? Why not? Because it doesn't help giving him back his life? Oh fine, then why put rapists in jail? Won't magically turn back the time as well. Same for murder charges. The victim is dead, putting the murder in prison won't bring the victim back to life.
Letting her pay money for it would just be the easy way out. Would it be okay, if a rapist paid the victim money instead of going to jail? No? So why should that be accepted in this case?
