Rape is a horrible, despicable act that can leave people with permanent emotional and physical scars. It destroys lives.

Being falsely accused of rape will leave you permanent emotional scars and destroys lives.

They aren't the same thing, but in both cases you have clear intent to harm someone else in a way that you know will destroy their life. A rape charge shouldn't be lessened, but the others should be worse. "20 years max" is weak. 5 years for the wife is pathetic too.
